Technologies of Manipulation During the Presidential Elections of 1999 in Ukraine
Authors: Konet Andrii
Published: January 2022

The article examines the election campaigns of the late twentieth century. in Ukraine and proved, that they operated manipulation technologies. The state was democratizing the political system, adoption of new election legislation, transition to a mixed electoral system; political pluralism was formed, the number of parties has increased significantly, the struggle for power intensified. With each subsequent election campaign (presidential, parliamentary), the political struggle intensified, and voter engagement technologies have become more vulnerable.

The author proves, that the ways and purposes of application of technologies depend on motivations of subjects of the power, as: obtaining, exercising and retaining power; the desire to achieve political and social results, most profitable for pragmatic actors, although this may run counter to collective goals.

In Ukraine, democratic processes are not yet complete, traditions of democracy and stable political institutions are absent. Instead, manipulation technologies, electoral engineering, which are aimed at limiting the actions of competitors and creating favorable conditions for their own victory. This prevents the formation of certain restraints, barriers to manipulation technologies, familiar to many civilized democracies.
Theoretical and Methodological Features of Europeanization and New Institutionalism
Authors: Klym Ruslana
Published: January 2022

It is identified in the paper that one of the important prerequisites for implementing an effective European integration policy is to consider the theories of Europeanization and new institutionalism. The essence of the concepts of "Europeanization" and "new institutionalism" is studied, the evolution of theoretical approaches to their research is considered, and the directions of studying "external" Europeanization were analyzed. The paper proves that the concept of Europeanization is widely used in the European scientific literature to analyze the political and regulatory influence of the European Union on new EU member states and neighboring countries, as well as the fundamental mechanisms of Europeanization. The author notes that Europeanization implies changes, transformations, and reforms taking place in all spheres of life under the influence of European integration processes, which can be analyzed from the standpoint of new institutionalism. The key provision of the new institutionalism is defined by the commonly used expression – "institutions matter", whose analytical priorities are to use a wide range of interdisciplinary approaches to the analysis of norms, institutions and processes.

Danach wird unter den Gesichtspunkten der politischen Opportunität und institutionalisierten Ungleichbehandlung verdeutlicht wie in der überkommenen Anwerbungs- und Ausländerpolitik mit der Frage der Integration umgegangen wurde. Im Anschluss daran wird das Verhältnis der neueren Integrationspolitik zu einer menschenrechtsbasierten Politik analysiert. Hier werden zunächst wichtige Elemente und Einflussfaktoren dieser Politik aufgezeigt. Zudem wird analysiert, welche Reichweite die Maßnahmen unter dem Gesichtspunkt menschenrechtlicher Verpflichtungen des Staates aufweisen, und angedeutet, wie eine Weiterentwicklung in Richtung des menschenrechtlichen Ideals der gleichen Freiheit erfolgen könnte.
MECHANICS AND ACOUSTICS OF METAMATERIALS: MATHEMATICAL MODELING, EXPERIMENTAL RESEARCH, PROSPECTS FOR APPLICATION IN MECHANICAL ENGINEERING
Authors: Erofeev V.I. , Pavlov I.S.
Published: January 2022

An overview of modern publications on acoustic and mechanical metamaterials is presented. The most important characteristic feature of metamaterials is the presence of frequency band gaps in them, i.e. such frequencies at which the waves cannot propagate in the material. This feature has played a major role in the creation of acoustic metamaterials that are successfully used to absorb sound, to damp vibration and shock effects, and to make devices preventing the propagation of waves on a given frequency in certain directions.

Such representatives of mechanical metamaterials as auxetics – materials, at least one of the Poisson's ratios of which is negative, have also proven themselves as advanced materials for practical applications. They are distinguished by high consumer value (low density, high strength, nice insulating properties).

In addition to acoustics and mechanics, in recent years there has been a significant increase in interest in the creation of materials that make it possible to control the flow of light or electromagnetic waves.

It has been also noted that the development of new metamaterials is in high demand for the aerospace and automotive industries, as well as for biomedical applications.

Two basic methods for modeling of metamaterials are considered: the continual-phenomenological description and the structural modeling. Their advantages and disadvantages are listed. The structural modeling method enables one establishing an analytical relationship between the medium macroconstants and its microstructure parameters. As a result, there appears a possibility both to get an idea of the qualitative influence of the microstructure of the medium on its effective elastic moduli and to estimate quantitatively these constants, as well as to find the ranges of values of the microstructure parameters at which the medium possesses unique physical and mechanical properties.
ON AUTOMATIC SEGMENTATION METHOD USING IN SOLVING NONLINEAR INITIAL BOUNDARY VALUE PROBLEMS OF MECHANICS OF SOFT-SHELL STRUCTURES
Authors: Korovaytseva E.A.
Published: January 2022

An approach to improving nonlinear initial boundary value problems of thin-walled structures solution algorithm is represented in the work. The algorithm is based on using line method and parameter differentiation method and is oriented to analysis of composite structures behavior at arbitrary physical and geometrical nonlinearity. Obviously, the less restrictions the calculation algorithm imposes on problem statement, the more features of its realization must be taken into account when developing corresponding software module. The drawback of universality of the algorithm represented is that its direct implementation in some cases can lead either to wrong results, or to loss of calculation stability. To avoid these problems we suggest automatic segmentation method using as a step of the algorithm developed. The essence of the method lies in testing fulfillment of the condition of normalized integral matrices of initial and conjugate differential equation systems orthogonality at the step of problem preprocessing. In the points of integration interval where orthogonality condition is not fulfilled segmentation of the interval is carried out. For testing this approach we select nonlinear problems of dynamic inflation of an infinite cylinder of Mooney-Rivlin material and a sphere of Neo-Hookean material by suddenly applied pressure. It is shown that automatic segmentation method allows improving period and amplitude calculation accuracy, as well as increasing iteration process convergence rate. A problem of dynamic inflation of a hinged hemisphere of Neo-Hookean material by suddenly applied pressure is considered. On the basis of its solution results we suggest the approach to determining parameters of calculation algorithm which allow obtaining correct solution.

Published: January 2022

Investigation of the function of the relative volume of pores under the load action is carried out on the base of the solution of the static contact problem of the indentation of a layer made of a material with voids or unfilled pores. A rigid strip indenter with a flat base is pressed into a porous layer that is adhered to a non-deformable base along the lower boundary. The formulated 3D problem of the indentation of a porous layer is reduced to solving the plane contact problem of the indentation of a porous strip. The plane contact problem is reduced to solving an integral equation for unknown contact stresses, the solution of which is constructed by the method of successive approximations in the form of an asymptotic expansion in the dimensionless parameter of the problem. The obtained contact stresses and the force acting on the indenter made it possible to study the influence of the nonclassical moduli of the layer porous material (the connectivity modulus and pore rigidity modulus) on the main contact characteristics and on the distribution of the function of the relative pore volume. The connectivity modulus increase leads to an increase in the compliance of the layer porous material, the pore rigidity modulus increase leads to an increase in the rigidity of the layer porous material. The maximum value of the distribution function of the relative pore volume in the porous material of the layer is achieved under the indenter base centre, regardless of the change in the porous material non-classical moduli.
On the Expressive Power of Non-deterministic and Unambiguous Petri Nets over Infinite Words
Authors: Finkel Olivier , Skrzypczak Michał
Published: January 2022

We prove that ω-languages of (non-deterministic) Petri nets and ω-languages of (nondeterministic) Turing machines have the same topological complexity: the Borel and Wadge hierarchies of the class of ω-languages of (non-deterministic) Petri nets are equal to the Borel and Wadge hierarchies of the class of ω-languages of (non-deterministic) Turing machines. We also show that it is highly undecidable to determine the topological complexity of a Petri net ω-language. Moreover, we infer from the proofs of the above results that the equivalence and the inclusion problems for ω-languages of Petri nets are ∏21-complete, hence also highly undecidable. Additionally, we show that the situation is quite the opposite when considering unambiguous Petri nets, which have the semantic property that at most one accepting run exists on every input. We provide a procedure of determinising them into deterministic Muller counter machines with counter copying. As a consequence, we entail that the ω-languages recognisable by unambiguous Petri nets are △30 sets.
Automated Repair of Process Models with Non-local Constraints Using State-Based Region Theory
Authors: Kalenkova Anna , Carmona Josep , Polyvyanyy Artem , La Rosa Marcello
Published: January 2022

State-of-the-art process discovery methods construct free-choice process models from event logs. Consequently, the constructed models do not take into account indirect dependencies between events. Whenever the input behaviour is not free-choice, these methods fail to provide a precise model. In this paper, we propose a novel approach for enhancing free-choice process models by adding non-free-choice constructs discovered a-posteriori via region-based techniques. This allows us to benefit from the performance of existing process discovery methods and the accuracy of the employed fundamental synthesis techniques. We prove that the proposed approach preserves fitness with respect to the event log while improving the precision when indirect dependencies exist. The approach has been implemented and tested on both synthetic and real-life datasets. The results show its effectiveness in repairing models discovered from event logs.
A Congruence-Based Perspective on Finite Tree Automata
Authors: Ganty Pierre , Gutiérrez Elena , Valero Pedro
Published: January 2022

We provide new insights on the determinization and minimization of tree automata using congruences on trees. From this perspective, we study a Brzozowski’s style minimization algorithm for tree automata. First, we prove correct this method relying on the following fact: when the automata-based and the language-based congruences coincide, determinizing the automaton yields the minimal one. Such automata-based congruences, in the case of word automata, are defined using pre and post operators. Now we extend these operators to tree automata, a task that is particularly challenging due to the reduced expressive power of deterministic top-down (or equivalently co-deterministic bottom-up) automata. We leverage further our framework to offer an extension of the original result by Brzozowski for word automata.

Published: January 2022

Inclined uniform magnetic field and mixed convention effects on micropolar non-Newtonian nanofluid Al2O3 flow with heat transfer are studied. The heat source, both viscous and ohmic dissipation and temperature micropolarity properties are considered. We transformed our system of non-linear partial differential equations into ordinary equations by using suitable similarity transformations. These equations are solved by making use of Rung–Kutta–Merson method in a shooting and matching technique. The numerical solutions of the tangential velocity, microtation velocity, temperature and nanoparticle concentration are obtained as functions of the physical parameters of the problem. Moreover, we discussed the effects of these parameters on the numerical solutions and depicted graphically. It is obvious that these parameters control the fluid flow. It is noticed that the tangential velocity magnifies with an increase in the value of Darcy number. Meanwhile, the value of the tangential velocity reduces with the elevation in the value of the magnetic field parameter. On the other hand, the elevation in the value of Brownian motion parameter leads to a reduction in the value of fluid temperature. Furthermore, increasing in the value of heat source parameter makes an enhancement in the value of nanoparticles concentration. The current study has many accomplishments in several scientific areas like medical industry, medicine, and others. Therefore, it represents the depiction of gas or liquid motion over a surface. When particles are moving from areas of high concentration to areas of low concentration.

Published: January 2022

For avoiding the damage of the insulation and permanent magnet, the temperature rise of the PMSM (permanent magnet synchronous motor) should be controlled strictly, it is usually one of the main objectives during improving the output power and torque density beyond the state-of-the-art in motor design. In this research, the coolant channel will be placed within the yoke of the stator core to enhance the heat transfer between the stator core and the coolant. Hydrophobic coating is applied to replace the metal tube for increasing the utilization of the cross area of the coolant channel. The impact of the coolant channel on the performance of the permanent magnet motor is analyzed. A general design method of the coolant channel is presented. The result shows that the change of the stator core loss is within about 10% as the coolant channel is moved away from the slot along the radial direction while the back electromotive force of the motor could keep constant through appropriate design. The impacts of the coolant channels on the magnet performance and the heat dissipation performance could be divided completely with the design method. The method can be applied on various PMSM including SPM (surface-mounted permanent magnet motor) and IPMSM (interior permanent magnet synchronous motor). Sufficient coolant flow could be provide to help conduct the temperature rise of the motor.

BACKGROUND:

It has been reported that the quality of life and diet quality in individuals with rheumatological diseases are poor and may adversely affect the course of the disease.

OBJECTIVE:

This study aims to compare the quality of life and diet of individuals with Behçet’s Disease (BD) compared to healthy controls.

METHODS:

This study was planned as a case-control study, and 60 adult patients with BD were compared with age (±1) and sex paired match healthy controls concerning the quality of life and diet. Diet quality was assessed using nutrient adequacy ratio (NAR) and the mean adequacy ratio (MAR) values calculated from 24 h dietary food recall and obesity was also evaluated by various anthropometric measurements. The Short Form-36 Health Survey (SF-36) was used to evaluate the quality of life (QoL). In addition, the 24-hour physical activities were recorded to calculate physical activity levels (PAL). Data were analyzed by SPSS 25.0 via paired sample t-test and McNemar test. p < 0.05 was deemed significant.

RESULTS:

The findings showed that cases were more obese ( p = 0.005), less physically active ( p < 0.001), had lower QoL ( p < 0.01 for all subscales) and had higher Beck depression scores ( p = 0.001). Controls had higher means of energy ( p < 0.001), CHO% ( p = 0.025), fat% ( p = 0.004), and fiber ( p = 0.007) intake and mean MAR value ( p < 0.001).

CONCLUSIONS:

Compared to healthy controls, patients with BD were more obese, had lower QoL and lower diet quality. Therefore, people with BD should be evaluated for comorbid diseases and be supported by health professionals, such as dietitians and psychologists.

Published: January 2022

There are still many elementary schools that have not implemented an information system for processing student grades online because of the assumption that this is still not needed, even though in fact the use of computerized information systems can help schools in improving the academic process to be more effective and efficient. Information systems with web-based applications that are now often found still have shortcomings, namely the mobility of their use is still lacking compared to Android-based applications which are now easier to use and access anywhere. The use of web applications as a means for teachers to input values as well as an android application as a means for parents to be able to monitor their children's academic scores is considered to be the most appropriate solution in implementing this information system, but differences in platforms between Android and the web make it difficult for data to be integrated with each other. Therefore we need an interoperability system in order to integrate applications from different platforms. Then an android based academic score monitoring application was made with RESTful web service. The selection of the RESTful web service system itself is because this system applies the concept of a client server where the server to be created is a web-based application that is used by the school to input student grades, and the client application is an android application intended for parents / guardians of students to get information regarding the value of his child. The output of this research is an application system for monitoring the academic scores of elementary school students by implementing the RESTful web service system in its application as well as the results of the application testing questionnaire based on the usability aspect of the application with the final result of the application eligibility percentage of 87%.Keywords: Monitoring Student Values, Platforms, Information Systems.

Implementation of Visualization and Modeling Technologies for Transportation Construction
Authors: Harper Christofer M. , Tran Daniel , Jaselskis Edward
Published: January 2022

State departments of transportation (DOTs) increasingly use visualization and modeling technologies for delivering transportation projects across the United States. Advanced and innovative technologies have the ability to improve various construction processes and tasks while making the construction process more efficient and productive. Visualization and modeling technologies, which include building information modeling for infrastructure, light detection and ranging, virtual reality, and augmented reality, are becoming more commonplace in transportation construction. Yet, the use of these technologies varies among state DOTs. The intent of this study is to investigate the use of visualization and modeling technologies for transportation construction. This study employed a triangulation research methodology including an extensive literature review, survey questionnaire of DOTs, and seven case studies. Results of the study show that 92% of state DOTs use visualization and modeling technologies for construction. Then, 81% of DOTs use visualization and modeling technologies for constructability reviews, 38% use them for documentation of as-builts and simulating bridge and structure construction, and 35% use them for quality management, inspections, and monitoring progress of work. The main barriers to using visualization and modeling technologies include legal concerns with using digital models as contract documents, incompatibilities in software and hardware between the DOTs and contracted parties, and the appropriate knowledge, skills, and abilities required to use visualization and modeling technologies for construction. The findings from this study provides valuable information for state DOTs to approach their implementation and use of visualization and modeling technologies for transportation construction delivery.

Intercellular adhesion plays a role in cancer formation and protein has a key potential in maintaining cell adhesion, including syndecan-1. Meanwhile, oral cancer originates from the oral epithelium, which has an invasive and metastatic level. Its treatments involving chemotherapy and radiotherapy commonly leave unfavorable side effects, hence, suitable alternatives are needed. Natural ingredients are widely used as an alternative treatment for cancer, for example, Ganoderma lucidum (G. lucidum) which has anti-cancer and anti-angiogenic properties, induces apoptosis, stimulates an immune response, inhibits the degradation of Extracellular matrix (ECM), reduces inflammation, affects cell cycles, cytotoxic, and acts as an antioxidant.This study aims to determine the effect of ethanol extract from Ganoderma lucidum Cianjur isolate on syndecan-1 expression in KB CCL-17 oral cell cancer. This was an experimental study with a post-test only control group design, the treatment group used G. lucidum ethanol extract with a concentration of 2.12 μg/ml (P1), 4.24 μg/ml (P2), and 8.49 μg/ml (P3), while the positive control group used cisplatin with a concentration of 11.5 μg/ml (K1). In contrast, the negative control used aquadest (K0), while syndecan-1 expression was observed using the immunohistochemical examination.The highest syndecan-1 expansion rate was found in the treatment group with a concentration of 8.49 μg/ml. A significant difference was indicated by one-way ANOVA (p<0.05) between K0 - K1, K0 - P1, K0 - P2, K0 - P3, K1 - P1, K1 - P2, K1 - P3, P1 - P2, as well as P1 and P3. The administration of ethanol extract from G. lucidum Cianjur isolate increases syndecan-1 expression in KB CCL-17 oral cell cancer.

Development of an electric measurement system for rapid determination of the friction coefficient
Authors: Rónai László
Published: January 2022

Development of an electric measurement system for rapid determination of the friction coefficient is discussed in this paper. The electric system is capable to use with a ball cage guide bush unit. Two beam load cells are included into the system and the measured values of the forces are processed by microcontrollers. In the course of measurements, normal- and tangential forces of inner or outer surfaces of different enamelled specimens could be determined. A data acquisition program is developed to record the force values to a personal computer. Linear interpolation method is required to synchronize the values of the load cells, which is necessary to calculate the coefficient of friction.

This was a descriptive type of cross-sectional study conducted to identify the Characteristics /qualities of role model/ medical teachers as perceived by medical students and to identify the influence of role models in selecting subjects for their future career. This descriptive type of cross-sectional study was conducted during July 2019 to June 2020. A semi-structured, self-administered questionnaire was used to collect data. A total of 868 medical students of phase III and phase IV were the respondents of the study. All available students who were willing to participate in the study were selected and medical colleges were selected purposively. Study revealed that out of 868 respondents 741 (85.4%) had identified role models during the course of their studies and 127 (14.6%) respondents could not identify any role models. It was observed that 91% students opted for clinical subjects while 9% opted for preclinical and para-clinical subjects. With regards to their subjects of choice for future career 21.0% of the students preferred Medicine, followed by Surgery (20.0%), Gynecology (9.2%) and Orthopedics (3.8%).Two hundred and thirty-two (26.7%) of the students did not choose any subject for their future career. Regarding the influence of role models in selecting subjects for future career it was revealed that 334 (61%) respondents felt that role models had influence. Maintaining integrity and neutrality by role models was given the highest importance and general appearance of role model was considered least important by the respondents. (Not clear! is it Role Model Characteristics?).The academic institutes should make an effort to develop the role modeling of faculty by highlighting positive attributes of role models. Teachers should be made aware of the influence of role models on their future colleagues

Present status of portfolio based training and assessment in postgraduate residency program in Bangabandhu Sheikh Mujib Medical University (BSMMU): A quantitative approach
Authors: Paul Bijoy Kumer , Sarkar Sajuti
Published: January 2022

Since 2009, the portfolio has been a prerequisite for the evaluation of postgraduate residency programs at BSMMU. This descriptive cross-sectional study was conducted with the aim of investigating the current status of portfolio-based training and assessment in BSMMU`s postgraduate training program. Total 264 residents and 30 faculty members selected conveniently and completed the Likert scale-based questionnaire. A checklist was used for reviewing portfolios (n=33) those were preserved by residents. Study revealed that most of the respondents were male (68.6% of residents and 93.3% of faculty members). About 60% of residents have given positive views on presence of instruction and purpose about maintaining the portfolio. Several participants expressed concerns because the portfolio content is self-reported; it may include bias or inaccuracy. Regarding opinions of respondents on characteristics of portfolio, both of the respondents perceived high satisfaction on portfolio based learning, reasonable contents, and practicable and feasible use of portfolio (p<0.05) except regular updating (p<0.05) and comprehensiveness of portfolio. In line with ownership and motivation, faculty members (4.03) highly assumed that the portfolio completed by residents as requirement of the university than residents (3.22) and p<0.05). Residents did not agree that they worked on the portfolio during university deadline (2.89) whereas faculty members ((3.73) showed vary positive views in this regard. Concerning commitments to use the portfolio, both respondents have conveyed high expression (mean >3.5) on the relationship between residents and supervisors so the role of an available supervisor in direct observations of the residents and dedicated educational meetings, giving feedback and support, cannot be exaggerated. Relating to assessment of portfolio, overall views of the respondents have expressed poor to moderate views and faculty members (2.37 to 4.23) have less satisfaction than residents (2.88 to 3.73). Though there are so many constraints such as the lack of clear purposes and instructions, poor understanding regarding ownership, assessment issues, and confusion about educational impact in future, but the portfolio as a feasible and acceptable tool to train and assess clinical competence and clinical specialization. Study recommended for generic format of portfolio based training and assessment to be considered in Bangladesh context. All Stakeholders should be well oriented at the beginning for utilizing the portfolio (supervision, monitoring and assessment system).
