Published: July 2023

An industrial development is always followed by technological developments, especially in the textile industry which in the process cannot be separated with the help of machines. One of the negative impacts of this development is the noise from activities that use machines. Noise can be interpreted by the brain as a stressor or a trigger for stress. This study aims to determine the relationship between noise and work stress on operators at PT Kusumaputra Santosa. This type of research is analytic observational with a cross sectional approach. The sample of this study were 43 workers in the spinning division at PT Kusumaputra Santosa. The sampling technique in this study used a purposive sampling technique. To measure noise using a Sound Level Meter (SLM). While the bivariate analysis technique used to determine the correlation between noise and work stress is the Somers'd test. The results of the study using the Somers'd test showed that there was a correlation between noise and work stress on the spinning operator with a p-value of 0.000 and correlation (r) = 0.516 (medium correlation strength). Suggestions for further research need to add other variables or factors that can affect work stress that have not been studied in this study, such as work relations, organizational structure, work atmosphere and work climate. For companies, it is necessary to upgrade personal protective equipment with better quality than before and comfortable to wear and for spinning workers, they need to wear earplugs that have been provided by the company.

Published: July 2023

In today's world, network security is a key issue of information security. Virtual Networks have become an integral part of modern IT infrastructure, which presents us with challenges in the field of security. One solution to this problem is the use of software-defined networking (SDN), which provides a means to control and manage network traffic. However, as with any technology, SDN has its vulnerabilities that must be considered when deploying it. One of the tools that helps to take into account the vulnerabilities of network infrastructure is the Common Vulnerability Scoring System (CVSS) standard. It allows you to quantify the level of vulnerability of the infrastructure, which enables effective network protection. Analysis of the CVSS standard is an important stage in the development of a network security strategy. This paper analyzes the standards for building software-configured networks. It is noted that SDN is a modern approach to the design, construction, and operation of information communication networks. Using SDN makes it possible to directly program and dynamically manage the network, as well as to abstract the functionality of the infrastructure layer. However, the growing interest in SDN has revealed the shortcomings of their application in the fight against cybersecurity threats. The SDN architecture itself, external malicious attacks, and insufficient access control and encryption tools were found to be the main security challenges. The use of secure routing tools based on vulnerability metrics is proposed to increase the level of SDN data plane network security. According to the conducted analysis of SDN data plane vulnerabilities and the functionality of routing tools, the authors recommend using the CVSS standard to quantify the level of infrastructure vulnerability during the development and research of promising approaches to secure routing in the data plane of software-configured networks.

Published: July 2023

The motion of electrons in a cylindrical magnetic field with the gradient-type potential is considered. The motion of electrons in the cylindrical magnetic field with the gradient-type potential is considered. It is found that in the selected field, the initial motion of electrons along the longitudinal axis is converted into motion along the radius. It is determined that such the transformation is due to the action of a solenoidal magnetic field with large longitudinal gradient. The transformation of the longitudinal direction of motion into the transverse one turned out to be stable in the energy range of 20...55 keV of electrons and in the range of 5...50 mm of radial dimensions of the particle beam. The main dependences of the motion of the electron beam in the given solenoidal magnetic field are studied with the help of the software tool. The results of numerical simulation of electron trajectories in the gradient magnetic field with the circular secondary emission cathode located in the middle of the system are presented. To study the mechanism of stability with respect to magnetic field, two experimentally realized magnetic fields were used. Based on these two fields, arrays of additional 4 fields are numerically synthesized. For the set of 6 named fields, the operation of the gun, in which the particle undergoes the stable transformation of the direction of motion, is numerically studied. It is shown that for the given electron energy and the fixed magnetic field, the parameter that determines the rotation of the particles is the magnetic field gradient at the boundary of the entry region. It is found that the rotation effect takes place for the considered range of radial beam sizes, which leads to particle focusing. The possibility is shown to control the vertical coordinate of the focused beam on the basis of the field adjustment, thereby giving the interpretation of the pore dependence of the registration of electrons on the detector. The dependence of the formation of the final distribution of particles on the amplitude and gradient of the magnetic field along the axis of the system is studied. The results of numerical simulation on the motion of the electron beam are presented. Based on the model of electron flow motion, the characteristics of the resulting electron beam are considered. It is shown that the beam, having radial dimensions of 5...50 mm, is transformed and focused vertically on the area of 1 mm.

Published: July 2023

An analysis of the possibility of implementing the most promising methodologies aimed at creating the infrastructure of a "smart" region was carried out. A detailed study of research-relevant scientific intelligence allows us to highlight the best developments. Many researchers focus only on the theoretical aspect of the issue. The authors of the article analyzed the principles of creating an information technology platform designed to facilitate the process of interaction of a resident of the region with the surrounding infrastructure. The formation of a "smart region" is designed to ensure active communication between representatives of various spheres of the agglomeration, i.e. local government bodies and various branches of the region’s functioning. It is the cooperation of these important life support links of the conglomeration of settlements that allows the development of a strategy aimed at improving living conditions and efficient use of resources. Today, there are already a number of successful examples of the formation of a certain basis and the laying of successful foundations for the development of "smart regions". It is the analysis of the best methods with the goal that becomes the basis of the application for the implementation of the "Smart Region of Zakarpattia" concept and the development of its own innovative information technology platform for the implementation of "smart" environment technologies. It is through the development of a high-quality information technology platform that the smart region is managed in order to improve the quality of services offered to citizens and make all management processes more efficient. In order to find the most optimal way of designing and meeting the community’s requirements, a recommendation system for selecting information technologies and their implementations is being developed, and as a result, we should get a balanced, optimal application model for the "Smart Region of Transcarpathia" information technology platform.

Published: July 2023

Mathematical models to solve optimization connection problems in nonsimply connected regions under typical technological restrictions on geometric and topological parameters of routes, first of all, on curvature and the number of bends, have been investigated and developed. The models are linked with the extant and prospective topogeodesic models of the territory polygonal images. The solution of connection problems involves search for optimum trajectories of routes and nets within unrestricted geometric shape areas. It needs the development of a plethora of general models as fields where connections are carried out. The connections can be of various types such as bendy, Manhattan, even, solid as well as routes of other types. Smeliakov and Pliekhova observe that the global and local regulation of geometric connections to solve connection problems can be presented as the general optimization connection problem that is defined as the problem of the choice of с, where W is a set of alternatives, R is a principle of optimality. In so doing, the set W can be presented as the totality of the phase space f and the restrictions Q that are applied to the parameters of the phase space f. In turn, it is expedient to imagine that the phase space f is the Cartesian product f = X*Y*Z*U of the output data X, disturbances Y, control parameters U and results Z. The analysis of problem indicates that first and foremost the effectiveness of the modelling of the phase space f is linked with the description of the output data X on the area F and space L of possible highways in F. This research is devoted to the solution of the problem to develop a model for connection tasks within the framework of geometric design.

Published: July 2023

For various channels of information transmission that can be used in local control systems of a wide range of processes, affordable, scalable, and inexpensive transmission methods are needed that allow the necessary information to be transmitted reliably without errors. Errors that occur in discrete, continuous communication channels are the main obstacle to the reliability of transmitted data. The main causes of errors are signal attenuation, noise and various interferences. As a result of the analysis of error statistics in discrete data transmission channels, it was concluded that single and double errors occur in the absolute majority of cases. It is proposed to combat errors by using tamper-resistant coding. Among the interference-resistant codes, redundant block-separated systematic codes are highlighted, among which is the Hamming code. The basis of the interference-resistant coding model is proposed to be the use of a systematic Hamming code followed by cascade coding by adding a parity check bit. The used model made it possible to deal with all the most likely cases of errors. Since this coding model must be flexibly used in different systems, a necessary criterion of the model is its universality. Therefore, the model was tested on a sample with code combinations of different numbers of bits. The purpose of this article is to analyze the dependence of the coding procedure execution time for encoders of different levels: a separate first-stage encoder, as well as a first-stage encoder with the addition of a second-stage encoder. Experiments were conducted with a large sample, which were subsequently analyzed and interpreted. Since the model proved to be flexible, simple, stable and effective as a result of experiments, and the process of combating interference by using cascade codes has proven itself well in world practice, it is recommended for use in various information management systems. The implementation of the coder for interference-resistant data transmission is given.

Published: July 2023

Mental model is an internal representation formed by individuals in explaining a concept. Previous research on mental models of bacteria concept has been carried out on university students, but has not been carried out on high school students. The purpose of this study was to analyze the mental model of high school students about bacteria using drawing-writing tests and concept map. This study uses a descriptive method with 30 students of class X in one high school in Bandung as respondents. Students' answers are then compared with the expert's mental model as the targeted mental model. Students' mental models through the drawing-writing test are categorized into five levels (levels 1-5), namely no pictures/writing, pictures/writings are wrong or irrelevant, pictures/writings are partially correct, pictures/writings have some errors, pictures/writings correct and complete. Students' mental models through concept maps are categorized into four levels (levels 1-4), namely emergent, transitional, close to extended, extended. The results showed that it was easier for students to represent the structure and reproduction of bacteria through pictures than writing. The students' mental models through drawing (D) and writing (W) were highest at levels D5 and W5 for the concept of bacteria structure and reproduction. The most dominant mental model level is D4/W2 for the concept of bacteria structure and reproduction. The lowest studentss’ mental model is D2/W2 for the concept of bacterial structure and D1/W1 for the concept of bacterial reproduction. Students' mental models through concept maps show that the highest level is level 3 (close to extended). The most dominant and lowest level of mental model is level 1 (emergent). The conclusion of this study shows that the mental model of students on bacteria was still not close to the mental model of experts.

Despite the most studies empirically reveal the advantages of teaching Socioscientific Issues (SSIs)  in catering the evolution of scientific knowledge and pedagogy in teaching science concepts better to meet the required competencies and students’ needs to develop appropriate skills and capabilities, the teaching of SSI-based is still obscure and new to the country due to science teachers find it difficult and unable to integrate in their classroom due  to lack of curricular resources, unfamiliarity, infrequent integration, and teaching trust issues which results to learning gap among students; inability to argument and less motivated to learning SSIs. A semi-detailed questionnaire was used to collect information such as teacher-student background knowledge on SSIs and SSI-based pedagogy,perception on the pedagogy and the need to develop SSI-based curricular resources. Interviews were done to selected teachers and students to highlight relevant and significant opinions. Furthermore, results revealed that science teachers and students are not acquainted with SSIs. Most teachers don’t know SSIs and don’t employ SSI-based lessons in their teaching resulting to zero experience among students to SSIs. Nevertheless, both teachers and student respondents asserted that the development of SSI-based curricular resources may  improve teaching and learning processes in science areas which may positively affect to students deeper understanding, science practices and argumentation.

O presente trabalho objetiva relatar experiências de aprendizagem vivenciadas por uma licencianda e dois professores atuantes em um curso de Licenciatura em Matemática, a partir do planejamento e execução de atividades desenvolvidas no âmbito do Programa Institucional de Formação de Professores do Instituto Federal Catarinense (PIFP/IFC). As atividades foram elaboradas com o objetivo de explorar o lúdico no processo de ensino e aprendizagem de tópicos da geometria plana abordada nos anos finais do ensino fundamental, utilizando o tangram e o geoplano, como recursos didáticos. O público-alvo para a aplicação das atividades foram duas turmas do oitavo ano do ensino fundamental de uma escola municipal, situada no oeste catarinense. Os resultados apresentados foram obtidos a partir da pesquisa qualitativa com dados coletados de anotações e observações realizadas pelos autores e do preenchimento de um questionário aplicado ao público-alvo e à professora regente da disciplina de Matemática. Segundo os autores, analisando o comportamento dos alunos, concluiu-se que a aplicação das atividades surtiu efeito positivo, já que ocorreu o envolvimento e o interesse dos discentes em todas as etapas do trabalho. Considera-se também que o uso de materiais lúdicos quando usados de forma pedagógica pode facilitar a aprendizagem dos conceitos matemáticos, de modo que os alunos desenvolvam o senso crítico ao explorar os conceitos de maneira experimental.

Accurate quantification of viable and non-viable bacteria is fundamental to most microbiological studies, thus, rapid and simple techniques are required for this purpose. The current protocol describes a procedure using the QUANTOM Tx™ Microbial Cell Counter (Logos Biosciences Ltd., Korea), a novel instrument for the quantitative measurement of total and viable microbial cells in a solution, using several bacterial species including Listeria monocytogenes, Escherichia coli, Campylobacter jejuni and Brucella species.
PASSIVE FIT OF CAD\CAM FRAMEWORKS DESIGNED BASED ON VIRTUAL IMPLANT POSITIONS VERSUS ACTUAL IMPLANT POSITIONS: A PILOT INVITRO STUDY
Authors: Kamel Mohamed El-Sayed
Published: July 2023

Aim: To evaluate the passive fit of CAD/CAM implant supported frameworks that are constructed before and after implant placement.
Methodology: A sample of 5 Kennedy class I models that loaded with 10 models bilaterally. In the first group, 3 implants were installed using full guided protocol and loaded with 3 units screw retained metal framework that constructed before implant placement based on virtual implant positions in aid of full digital work flow. While the second group was the control group, in which 3 implant were installed and loaded with 3 units screw retained metal frameworks constructed after implant installation based on their implant positions. The frameworks were screwed to multi-unit abutments seven tests were carried out to assess passive fit of the frameworks. These tests were visual, tactile test using examination probe, floss slippage, one screw test , screw resistance test and fit checker. Radiographs were done in conjunction with these tests to assess presence of gaps at abutment –framework interface.

Date palm (Phoenix dactylifera L.) is the sweetest edible fruit plant in the Kingdom of Saudi Arabia. The development of precise DNA fingerprints to identify cultivar's genetic diversity is most important for breeding programs. Genotypic variation among five different cultivars of date palm of the Al Ahsa governorate in Kingdom of Saudi Arabia was studied using random amplified polymorphic DNA (RAPD) markers by QIAxcel electrophoresis system. We test 20 RAPD primers among them 15 primers show banding pattern. We use clean younger leaves that had been gathered and grind with liquid nitrogen into a fine powder and used for extraction and ultimately the quality of the DNA. We examined the DNA extraction with the use of guide CTAB and automatic Qiagen EZ1 technique and tested using the UV gel electrophoresis the concentration of the DNA became examined with LABTRON Nano spectrophotometer. Four primers gave high levels of bands with numerous polymorphisms and multiple bands. A total of 165 bands were observed, including 89 polymorphisms and 4 monomorphisms. The Ruzeiz(RZ) breed is very closely related to Khalas(KH), but the recorded Ruzeiz(RZ) and Shebebi(SHB) breeds retain a high degree of genetic divergence between Hatimi(HT) and Shaishe(SH). The results of this study demonstrate that polymorphisms revealed using RAPD markers are genotype appropriate.
