Досліджено дискретизацію аналогового сигналу, що був отриманий від сейсмічного приймача СМ-3 під час проведення промислового вибуху. Інформація про сейсмічні коливання ґрунту в основі будівель і елементів самих споруд фіксувалась у вигляді осцилограм за допомогою персональних комп’ютерів типу ноутбук у комплекті зі стандартними сейсмоприймачами типу СМ-3 та швидкодіючими аналогово-цифровими перетворювачами типів Е-140 та Е-440. Оскільки в районах розміщення охоронних об’єктів майже постійно у сигналі зустрічаються фонові перешкоди (на частоті 20–50 Гц) і вони збігаються із робочим діапазоном стандартних сейсмоприймачів типу СМ-3 (від 0,5 до 50 Гц), то при вимірюванні сейсмічних хвиль цим комплексом потрібно застосовувати дискретизацію фонових перешкод, використовуючи метод низькочастотної фільтрації сигналів. Саме тому усі осцилограми, отримані під час промислових вибухів, мають фільтруватися на частоті 20–50 Гц. І лише після фільтрації отриманих сейсмограм можна проводити оцінку сейсмічної безпеки даних вибухів. Також під час проведення сейсмовимірювальних робіт для запису і порівняння протоколів сейсмічних вимірів використовували канадський комплекс MiniMate Plus. Таким чином, у роботі показано результати фільтрації аналогового сигналу та обґрунтовано доцільність спільного використання системи «сенсори – аналого-цифровий перетворювач – ноутбук» і комплексу MiniMate Plus.

Під час відокремлення монолітів від масиву алмазно-канатними установками зберігається його цілісність, але разом з цим виникають супутні проблеми та питання, такі як вибір оптимальних розмірів моноліту і кута буріння для заведення канату, або які механізми чи пристосування використовувати при відділенні моноліту від масиву. Процес відокремлення моноліту від масиву алмазними канатними установками здебільшого супроводжується виникненням кількісних втрат каменю, на які впливають такі параметри: кількість площин оголення моноліту, розміри моноліту, який вилучається, абсолютний діаметр буру, товщина алмазного канату. Якісні втрати під час використання алмазно-канатних пил майже відсутні. Однак на їх виникнення впливають такі чинники: відхилення канату від заданої площини пропилу, нерівномірне зношування алмазних втулок і зміна товщини алмазного шару в результаті його зношування під час різання.

Збереження та вдосконалення показників якості будь-якої продукції є актуальною науковою та практичною задачею для поточного виробництва, враховуючи вироби з природного облицювального каменю. У світі немає подібних родовищ природного облицювального каменю. Кожен з них є по-своєму неповторним. Однак для більшості родовищ природного каменю характерна природна мінливість якісних показників. Насамперед після обробки таких каменів з’являються відмінності у кольоровому тоні.Можливо надати інший кольоровий тон хімічною обробкою. В даний час існує багато хімічних методів обробки природного каменю. Однак більшість з них недостатньо вивчена. Тому оцінку впливу хімічної обробки на поверхню природного каменю досліджували за допомогою інфрачервоної спектроскопії. Встановлено лінійні закономірності зміни колірних показників природного каменю залежно від його початкових показників після хімічної обробки на прикладі Покостівського гранодіориту (Grey Ukraine) та Буківського габро (Galant).Окрім методу колірної сегментації, для оцінки відмінностей у типах природного облицювального каменю був використаний метод інфрачервоної спектроскопії, який показав, що Покостівський гранодіорит (Grey Ukraine) та Буківський габро (Galant) мають однакові довжини хвиль, що належать до спільного породоутворюючого мінералу – плагіоклазу. Зміна поглинання інфрачервоного випромінювання зумовлена ефектом порожнин і об’ємним розсіюванням променів у зв’язку з переходом через кристалізовану плівку хімічних просочувальних речовин. Для певного типу природного каменю зміна поглинання буде більшою чи меншою при використанні певного виду хімічної обробки, що вказує на міцний або слабкий зв’язок хімічних просочуючих речовин з поверхнею природного каменю відповідно.

Authors:   Centro Universitário Euro-Americano (UNIEURO)
Published: August 2021

Objectives: Describe vaccination coverage and measles incidence in Brazil from 2016 to 2019. Methods: Quantitative, descriptive and retrospective study of confirmed cases of measles and vaccination coverage in the last 04 years, in the regions of Brazil. The data were exported from epidemiological bulletins from all regions, made available by the Ministry of Health and State Health Secretariats. Immunization data were collected using Tabnet/DATASUS, and organized in Microsoft Office Excel® (2019). Results: During 2016-2017, Brazil did not report confirmed measles cases. In 2018, 10,322 cases were recorded, with a prevalence of 10.245 (99.25%) in the North, followed by the South 46 (0.44%) and Southeast 23 (0.22%). In 2019, 20,901 cases were recorded, with the Southeast region having the highest incidence, 18.426 (88.15%), followed by the South region with 1.468 (7.02%). Between 2016-2019, the vaccination average was 84.05%. In this period, the North region reached the lowest coverage, 75.79%, followed by the Northeast region, 80.31%. In 2018, the highest incidence of cases was observed in the North region, due to the lower vaccination coverage obtained in the last 4 years. In 2019, the majority of cases were in the Southeast region, because despite the satisfactory vaccination coverage, the disease spreads more easily in large urban centers. Conclusion: Despite the increase in vaccination campaigns, Brazil has not reached the minimum number of vaccinations, in the last 4 years, to obtain herd immunity, increasing the manifestation of the disease in the last 2 years.

Social exclusion is blockage or denied access of people from various rights, resources and opportunities (democratic participation, employment, housing, employment etc) that are normally available to other members of society. The outcome of social exclusion is limited economic, political and social life creating a barrier in the way of potential growth and development. The social exclusion of people is a big challenge for policy makers and researchers now days. This study is an attempt to find out the effects of trade liberalization and tax revenues on socially excluded people of Pakistan covering the time span of 1980-2016. The auto regressive distributed lag model is applied to determine the long and short run relationship among the variables. The findings of the study reveal that trade liberalization and per capita income has vital role to decrease the level of social exclusion while increase in tax revenues is increasing the social exclusion. Further globalization of the economy is suggested for social inclusion of the people.

The vehicle logo is one of the features that can be used to identify a vehicle. Even so, a lot of Intelligent Transport System which are developed nowadays has yet to use a vehicle logo recognition system as one of its vehicle identification tools. Hence there are still cases of traffic crimes that haven't been able to be examined by the system, such as cases of counterfeiting vehicle license plates. Vehicle logo recognition itself could be done by using various feature extraction and classification methods. This research project uses the Local Binary Pattern feature extraction method which is often used for many kinds of image recognition systems. Then, the classification method used is Random Forest which is known to be effective and accurate for various classification problems. The data used for this study were as many as 2000 vehicle logo images consisting of 5 brand classes, namely Honda, Kia, Mazda, Mitsubishi, and Toyota. The results of the tests carried out obtained the best accuracy value of 88.89% for the front view logo image dataset, 77.03% for the side view logo image dataset, and 83% for the dataset with both types of images.

Authors: Lorien Antika , Wellem Theophilus
Published: August 2021

The authenticity and integrity of documents are essential in data exchange and communication. Digital documents must be verifiable for their authenticity and integrity by all parties that use the documents. Generally, digital documents can be authenticated by using digital signatures. This study aims to implement a document authentication system based on Quick Response (QR) code and digital signature. As the case study, the document authentication system is implemented to generate digital signatures for student’s certificate documents. Furthermore, the system can also verify the authenticity of the certificate documents. Creating a digital signature requires a hash function algorithm for generating the message digest of the document. In addition, an algorithm to generate the public key and the private key used in the encryption/decryption of the message digest is also needed. The hash function utilized in this study is the Secure Hash Algorithm-256 (SHA-256), while the algorithm used for encryption/decryption is the Rivest-Shamir-Adleman (RSA) algorithm. The system is evaluated by verifying 30 student certificate documents, of which 15 of them were certificates with QR code signature generated by the system and the other 15 were certificates with QR code signature generated using a random QR code generator. The system’s testing results demonstrate that the system can ensure the authenticity and integrity of the signed certificate documents to prevent document falsification. All documents that contain random QR codes were correctly identified as false documents.

Published: August 2021

There is a well-known shortage of racial diversity in medical textbooks and literature contributing to race-based health care inequalities1. We present the case of a black puertorrican 58-year-old female who developed a painful non-pruritic blistering ulcer in the inner oral mucosa with associated erythema six months prior to the evaluation. She was misdiagnosed on multiple occasions leading to a rapid progression of the disease, and subsequently, her death. Lack of images in medical textbooks and scarce literature describing initial presentation per-skin-tone of Pemphigus Vulgaris (PV) in patients with dark skin color led to misdiagnosis, delay in treatment, and thus, this catastrophic outcome. This case report describes the appearance of PV in patients with dark skin tone and serves as an educational resource by providing images of a rare skin disease in people with dark skin. The purpose of this case report is to fill major gaps in medical literature, highlight the importance of timely recognizing PV in patients with dark skin, and to create awareness among physicians.

Web Application Authentication Using Visual Cryptography and Cued Clicked Point Recall-based Graphical Password
Authors: Kenneth Mary Ogbuka , Olujuwon Stephen Michael
Published: August 2021

Alphanumerical usernames and passwords are the most used computer authentication technique. This approach has been found to have a number of disadvantages. Users, for example, frequently choose passwords that are simple to guess. On the other side, if a password is difficult to guess, it is also difficult to remember. Graphical passwords have been proposed in the literature as a potential alternative to alphanumerical passwords, based on the fact that people remember pictures better than text. Existing graphical passwords, on the other hand, are vulnerable to a shoulder surfing assault. To address this shoulder surfing vulnerability, this study proposes an authentication system for web-applications based on visual cryptography and cued click point recall-based graphical password. The efficiency of the proposed system was validated using unit, system and usability testing measures. The results of the system and unit testing showed that the proposed system accomplished its objectives and requirements. The results of the usability test showed that the proposed system is easy to use, friendly and highly secured.

Clinical reasoning is the thinking and decision-making processes associated with cognitive process and clinical practice of the health professionals. The main purpose of the study is management of case with aphasia by the three-track reasoning. Clinical reasoning is central to effective, efficient clinical practice and professional autonomy. Health professionals are accountable for their decisions and service provision to various stakeholders, including patients, caregivers, health sector managers, policy-makers and colleagues. An important aspect of this responsibility is the ability to clearly articulate and justify management decisions in a manner appropriate to the audience. However, clinical reasoning is not a skill that can be simply explained, understood and recalled because of its rapid, complex and often subconscious nature. For providing diagnosis and providing intervention as well as socially rehabilitate to the patient three reasoning is very important.

The article is devoted to a consideration one of the phenomenon gender culture modern citizens – the marriage strategies. This work is based on materials of semi-tructured interviews with young Perm’s families. The information received is 13 case-studies – detailed stories about a marriage choice, a marriage party and elements of family’s daily life. Using the theory gender study and case-study the author divided that materials into some groups of marriage strategies. Criteria of this operation were features of a respondent’s gender identifications. This paper considers a perversion marriage strategy. The type of strategy understood as a woman’s gender domination in matrimonial practices in further marital life. And then the author describes two cases illustrating it. A narrative is the form of the strategy’s presentation. This is a storytelling of major marriage practices of characters with their comments. The first narrative describes a «soft» variant of the perversion marriage strategy. An initiative of a woman combines with her performance a traditional «woman’s» role: she does housework and uses man’s material resources. The characters have contrast personality traits. They take turns setting the rules in the relationship and sometimes objectify each other. The second narrative shows a «hard» variant of the perversion marriage strategy. In this story man has a need for the approval of his actions and a woman has it too. Also, she has tendencies to dramatize. The woman plays a leading role in a relationship. She controls a man’s lifeworld and lets him take minor decisions. Both narratives reconstruct two versions perversion marriage strategy and show one of the potential model modern gender culture.

Published: August 2021

Problem statement. The beginning of the production of vegetables in protected soil on an industrial basis in Ukraine was marked by the construction in the 80s of the last century of greenhouses from the structures of the Antratsyt Luhansk region prefabricated greenhouse plant. A new impetus to the development of greenhouse vegetable growing was provided by the commissioning of energy-saving modern winter greenhouses built in the period from 2005 to 2015. Greenhouse vegetable growing is not standing still, but is actively expanding around the world. Further development of this area is possible with the introduction of new technologies for construction and operation of greenhouses, as well as their design solutions. The development of greenhouse vegetable growing is an important economic task. The design and technological features of modern greenhouses of the fifth generation of the semi-closed type are shown, which allow to provide high yields at lower consumption of material resources. A study of the complexity of the construction of greenhouses, identified low-mechanized, manual processes. The purpose of the article is to show ways to improve the design and technological parameters of modern greenhouses. In order to ensure energy savings and increase yields. Results. The analysis of normative documents on design and construction of greenhouses is performed. It is shown that greenhouses, the so-called "semi-closed type", allow to obtain high vegetable yields and energy savings. The most mechanized processes for the construction of greenhouses are earthworks and foundations. Much of the manual labor takes place during the installation of the metal frame, glazing and heating systems. Scientific novelty and practical significance. For the first time the value of labor intensity and duration during the construction of greenhouses was obtained, their dependences on the main factors influencing the performance of construction and installation works were established. This allows at the stage of development of design and technological documentation to determine rational ways of performing work.

Published: August 2021

Raising of problem. The methodology presented in this study is aimed at modeling the variability of the technical condition when operating a car in a complex social and technical system "car − person − environment". This allows you to simulate the change in the operational properties of the car depending on its operation, affecting the change in the technical condition by the Functional Resonance Analysis Method (FRAM). Purpose. The variability of the technical operation of the car needs to be managed, and not reduced or eliminated, since this is an advantage, as well as conditions for the safety and functioning of complex socio-technical systems. To control it, you must first monitor the variability of the vehicle's technical operation. A set of relevant indicators needs to be identified and developed. Their interpretation makes it possible to draw conclusions about the level of technical condition, operational properties of the vehicle and traffic safety and supports the prediction of the occurrence of future events (failure occurrence). Conclusion. Thus, the basic principles of the FRAM for modeling the variability of the technical condition when operating a car in a complex social and technical system "car − person − environment" have been determined. The relationship has been established between the definition of traffic safety, the FRAM model and the performance indicators of the vehicle.

ormulation of the problem. The paper examines the gender transformation of education in the field of architecture and construction and conducts a thorough analysis of gender equality of students of the Dnieper State Academy of Civil Engineering and Architecture (PSACEA) when entering various faculties. Purpose: to investigate the gender equality of PSACEA students. Objectives: 1. To analyze the opportunities of women to receive higher technical education in different historical periods. 2. Investigate the ratio of boys and girls among full-time students of PSACEA when entering various faculties, as well as the opportunity to receive a scholarship. During the study, the data of 2214 PSACEA students as of February 2020−21 academic year were analyzed. Theoretical analysis and generalization of scientific and methodological literature were conducted to study the trends of gender transformation of education in different historical periods. Particular attention was paid to the study of women's opportunities for education in the field of architecture and construction. During the study, experimental data were processed using conventional methods of mathematical statistics. Conclusions: The study allows us to establish the gender equality of students in PSACEA. The analysis of publications showed that in previous historical periods, the representatives of the architectural and construction industry were mostly men. The growing number of girls in traditionally “male” specialties in the field of architecture and construction requires the modernization of educational programs and material and technical base and their adaptation to the capabilities of students of different genders, which can positively affect the encouragement of applicants during the introductory campaign.

Formulation of the problem. The problem of adaptation of students to institutions of higher education in our time is of great scientific and practical importance. The breakdown of dynamic stereotypes during the transition from the school system to higher education, the change in living conditions for nonresident students, a new social environment − all this accompanies the freshman and requires the formation of psychological mechanisms of adaptation of the personality of yesterday's schoolchild to new conditions of life and activity. The purpose of the research: determination of the structural components of the adaptation process, determination of the main directions of optimization of the adaptation process, creation of a multifunctional model of the student's adaptation process to the university. Conclusions. The main goal of optimizing the process of adaptation of a student to the university is to create conditions for the development, self-improvement and disclosure of the creative potential of the student's personality. So, we see the same ways of solving the indicated problems: psychological and pedagogical training of the supervisors of student groups; introduction of innovative technologies in the pedagogical process; improving the psychological and pedagogical qualifications of the teaching staff of a higher educational institution; work with gifted youth, development of students' creativity in the learning process; development of student initiative and self-government; psychological support of methodological and educational work in a higher educational institution; psychological support for the development of the student's personality in the learning process: mastering the skills of independent work, communication skills, disclosing the psychological characteristics of the development of one's creative potential, solving personal problems.

Problem statement. The analysis of accident causes, which can take place both at the production site and within living environment, connected with social, economic and psychological working conditions is carried out in the article. Violation of these conditions can be a reason of equally hard both physical and psychological traumas at work areas in any manufacturing sector. Working conditions, which form during work and during the contact with colleagues at work places are envisaged. Factors, effecting on human activity during work were analyzed. Psychological and physiological limits of working environment are envisaged. The evaluation of the work bench is realized with allowances made for the influence of all factors of manufacturing environment and working process and on the grounds of complex evaluation of working place it is indicated, that one or another work place is relating to specific types of working environment. Main factors of working environment, influencing of human performance capability during working process are described. Psychological and social aspects of the increase of occupational safety level are presented. Recommendations concerning organization of safe behavior of workers during labor are provided. Work place is evaluated taking into consideration the influence of all manufacturing factors and working environment on workers, on the grounds of which one or another work place is related to corresponding type of working conditions. It is shown that to the deduction of the effect of psycho-physiologic safety concerns during working process it is necessary to take into account individual qualities of the worker, such as errors, and also unfavorable accidents, arising from the encounter of human’s qualities with specific aspects of specific professional activity. With the purpose of the improvement of safety and health protection of workers during labor it is necessary to realize professional psycho-physiological selection for wide range of professions. Object. Determine connection between psychological, social and economic aspects and probability of professional injuries or professional disease at work places in manufacturing environment. Conclusion. The analysis of psychological, social and economic bases of occupational safety and the influence on injury rate is carried out.

Published: August 2021

Formulation of the problem. Operation of buildings and structures is based on periodic assessment of the condition of structures. The procedure for determining the strength of concrete by non-destructive methods requires a certain preparation of the concrete surface of the structure and sampling in order to calibrate the devices. During sampling, the samples may be damaged, in addition the surface of the cylinders does not meet the requirements for normalized test conditions. Part of the cores during selection is being destroyed, which reduces the representativeness of the results of determining the physical and mechanical properties of concrete. The purpose of the article is to find out the possibilities to increase the reliability of determining the physical and mechanical properties of concrete. Results. In the conditions of a real object, core samples were taken to study the concrete strength of the damaged area. Samples that did not meet the normalized parameters were prepared for testing using a repair mixture Mapegrout Thixotropic. Testing of the recovered core samples showed that the repair mixture adhered well to the surface of the core. The nature of the destruction in the restored and normalized samples is similar. Conclusions. Studies have shown that: the application of the existing method of determining the strength of concrete for slab structures limits the possibility of using core samples taken from structures; the use of Mapegrout Thixotropic repair mixture allows to carry out tests according to the normative method of damaged concrete samples or samples rejected due to size mismatch; reliable assessment of the deformable properties of concrete cores in many cases is impossible; the existing methodology needs to be improved or replaced by an alternative one; quantitative assessment of the rheological properties of the concrete mixture used for the manufacture of concrete structure is possible on the basis of comparing the deformable and strength characteristics of concrete structure, which requires formalization of the procedure and standardization.

Problem statement. The problem of improving the learning process can be solved by increasing the educational collections of minerals and rocks that can be found every day, but for various reasons, do not pay attention to them. The best samples of various stone materials were usually used for cladding. Similarly, in the external and internal cladding of the academy buildings were used varieties of rocks that differ in strength, color, texture, structure and inclusions of minerals and are the best examples of decorative building materials. Purpose of the article. All this diverse stone decoration of the Academy can be used in the educational process, in particular, for the study of minerals and rocks within the discipline “Engineering Geology”, which is read to all students of the Faculty of Civil Engineering and Architecture, as well as the Faculty of Civil Engineering and Ecology. Conclusion. All this diverse stone decoration of the Academy is quite possible to use in the educational process, in particular, for the study of minerals and rocks in the framework of teaching the discipline “Engineering Geology”, which is read to all students of the Faculty of Civil Engineering and Architecture, as well as the Faculty of Civil Engineering and Ecology. Thanks to the polished surface of large slabs of facing rocks, it is possible to visually and more fully identify rocks while studying the relevant disciplines, which is convenient for teaching students of all specialties. It is expedient to use facing materials of buildings of educational institution in the course of studying of geological disciplines, especially for students-architects for what it is necessary to provide target excursions on buildings of academy. Various rocks, with which the interior elements are faced, serve as a good addition to the existing educational collections of the Department of Engineering Geology and Geotechnics.
