Authors: Lapina M. A.
Published: July 2022

The paper aims to substantiate the main development directions of legal regulation of artificial intelligence in healthcare. The main hypothesis of the study is the assumption that artificial intelligence should not be a subject of law. The author formulates the postulates necessary for the introduction of modern technologies in the context of the digitalization of medicine. General and special scientific methods are used: the dialectical method of cognition of reality, synthesis and deduction. The comparative and formal legal method of scientific cognition made it possible to analyze the laws and other documents of a number of states in the field of digitalization and the mechanism for financing the provision of medical services and medical care. The article analyzes the directions proposed by scientists and practitioners with the participation of the largest IT companies to improve the provision of medical care and medical services and optimize healthcare management. The author draws attention to financial mechanisms to stimulate the introduction of digital technologies in the healthcare system, directly to the provision of medical care. Structuring the main directions of applicability of digital technologies in healthcare allowed us to formulate proposals for improving their legal support. The analysis of foreign and domestic legislation has revealed the importance of using such a financial and legal mechanism as health insurance. Based on the results of the study, the author makes a conclusion about the need for a systematic approach to digitalization in healthcare and proposes an institutional and legal model for the development of patient-centered medicine based on artificial intelligence technologies.

Authors: Ismoilov G. N.
Published: July 2022

The subject of the research is the segments of the financial system of the Russian Federation: the budget system, the banking sector, the stock and insurance markets, and the currency policy of the state. The purpose of the study is to determine the trends and factors in the development of the main elements of the financial system at the present stage. The relevance of scientific research is due to the fact that the financial system is a key element of the strategy of socio-economic development of any state, providing economic processes with financial resources and capital. The author uses the following methods: analysis, synthesis, generalization, and the logical method. The study highlights promising directions, ways and mechanisms for the development of the Russian financial system that are relevant in the 2020s. The key factors influencing their trends and threats that create barriers are analyzed. The main directions, ways and mechanisms for stimulating the further development of the elements of the financial system are described. The author concludes that due to the spread of the coronavirus pandemic and economic sanctions imposed on Russia, the stability of the Russian financial system has been violated, which requires the adoption of state regulation mechanisms to improve the activities of financial institutions. The prospect of further research on this topic may be related to the development of areas for improving individual elements of the Russian financial system.
Lexemes iç, içeri, dış, dışarı in Modern Turkish Language
Authors:   Moscow State University, Moscow, 119991 Russia, Napolnova E.M.
Published: July 2022

This article deals with the semantics of the Turkish lexemes: iç and içeri, related to the internal part, internal space, or the contents of an object; dış and dışarı, correlated with the external part, the surface of the object, and with everything that surrounds it from the outside. Their morphological, syntactic, and compatibility features were considered. The relevance of the research carried out using the corpus method stems from the fact that lexical semantics (in the broad sense of the term) is one of the priority areas of modern linguistics because it studies the conditions for the correct construction of statements that are not determined by grammatical and syntactic norms. The analysis yielded the following results: the four lexemes under study are typically used with possessive suffixes when they perform the nominal function; the presence of ancient indicators of directionality in içeri and dışarı underlies their predominant use in the adverbial function; the very high frequency and wide lexical compatibility of the lexemes iç and içeri arise from the key role played in the linguistic consciousness of Turkish speakers by the idea of the internal space/filling of objects as a special entity that determines the state and possibilities of using the object. For the space external to the reference point, on the contrary, it is not a description of its state that is important, but a more accurate indication of the position of objects, which is associated with the possibility of reaching them and is enabled by the presence of a clearly structured system of tokens with spatial meaning. This is expressed in the lower frequency of the lexemes dış and dışarı and the formation of the meaning ‘outside’ in the possessive-marked postposition function. The conclusions obtained are of both practical importance for teaching the language and can be efficiently used as a promising material for typological lexico-semantic research, especially in what concerns the directions of development of the vocabulary of the Turkic languages.

This article considers how children’s neuropsychological development, in particular executive functions, influences their speech acquisition. The study involved 71 students of the second grade (average age 8.8 years, standard deviation 0.29) in one of the lyceums in Moscow. The children were asked to do tasks based on a battery of neuropsychological methods, including making up a story using a series of pictures “Garbage”. The results of the neuropsychological tests were used to calculate the following parameters: firstly, the index of the executive functions (3.1) and the index of serial organization (3.2); secondly, the auditory information processing index (2.2) and the left hemispheric index (L); and, thirdly, the visuospatial information processing index (2.4) and the right hemispheric index (R). According to these indices, strong and weak groups were formed 1) for executive functions, 2) for left hemisphere, and 3) for right hemisphere functions. The stories created by the children were used to analyze their speech production ability, as well as both general textual and syntactic parameters. The data obtained revealed that, depending on the level of development of executive functions, children’s stories differ in a number of parameters. The latter include general text features (semantic completeness, semantic adequacy (the presence of incompleteness and distortions), the construction of the semantic program of the story, the number of words in the story) and syntactic and grammatical features (the number of simple and complex sentences, the average sentence length, etc.).

Published: July 2022

This paper explores the potential of machine learning techniques to predict the soil water retention curve based on physical characterization parameters. Results from 794 water retention and suction points obtained from 51 different soils were used in the algorithm. The soil properties used are the percentages of gravel, sand, silt, and clay, the plasticity index, the porosity, and the relation between the volumetric water content and total suction. The data were used as input for machine learning estimators to predict the volumetric water content of a soil with specified physical characterization parameters and suction, the techniques of artificial intelligence were developed in python. Results show that an extremely randomized trees’ estimator can reach a coefficient of determination of 0.99 in the training dataset, with a coefficient of 0.90 in the cross-validation and testing dataset, which measures the generalization capacity. Furthermore, a continuous function can be obtained by fitting a model such as Cavalcante & Zornberg, or van Genuchten, or Costa & Cavalcante (bimodal) to the predictions of the machine learning for use in numerical methods. These results indicate that the proposed machine learning estimator can become an interesting alternative to estimate the soil water retention curve in engineering practice. This work is in progress and the predictions can be improved with the addition of new data. Know how to participate at the end of the paper.

In order to evaluate the performance of introduced varieties of maize and test them under different levels of plant density, and to determine which of the introduced varieties give a high yield and at what plant density, a field experiment was carried out at Station A in the Department of Field Crops- College of Agricultural Engineering Sciences - University of Baghdad- Jadiriyah, for the fall season 2021, the RCBD design was used with four replications, in a split plot arrangement, the three plant densities (50.000, 70.000, and 90.000 Plant s ha-1) were the main plates, while the varieties represented the secondary factor, which is six varieties of maize, class 2 = 5783 DKC, Class 3 = 6315 DKC, Class 4= 6590 DKC, which are introduced and compared with three local varieties: Fajr, Sarah and Al-Maha, The traits of yield components (the ear length, the number of rows ear-1, the number of grains row-1, the number of grains ear-1, the number of ears, the weight of 100 grain) and their relationship to the plant yield were studied, The plant density significantly affected all the studied traits except for the number of ears, it was not significant. Low plant density outperformed the highest plant yield (157.2 g) due to its superiority in ear length, number of rows ear-1, number of grains row-1, number of grains ear-1 and weight of 100 grains. The plant over the local varieties, especially variety 3, which gave the highest plant yield (168.2 g), followed by variety 4 (155.4 g), due to their superiority in ear length, number of grains row-1, number of grains ear-1, number of ears, and weight of 100 grains. The interaction between varieties and plant density was significant in all studied traits. We suggest planting the introduced varieties at different planting dates and locations to show their ability to environmentally imprint Iraq's climate and study them in the spring season, and test them under other abiotic stresses such as drought.

The purpose of the work is to determine the stress fields of the pipe in the dent area under bending load. The object of research was a pipe with the following geometric characteristics: an outer diameter 325 mm, a nominal wall thickness 9 mm, a length 3 m; a pipe steel grade is “14ХГС”. There is a dent on the pipe in the area of the pipe top line. Geometric parameters of the dent: length 240 mm, width 148 mm, maximum depth 11.8 mm, relative depth 3.6 %. The review of literary sources on the topic of the article is carried out. Insufficient study of the stress-strain state of the pipe in the dent area by means of physical and full-scale experiments using strain gauges and with a detailed determination of stress and strain fields was found. In the experimental part of the work a bending load in the vertical plane acted on a pipe with a dent. Using electrical resistor strain gauges measurements of hoop, longitudinal strains and strains at an angle of 45 degrees to the pipe axis in the nodes of the coordinate grid applied in the defect area were carried out. The fields of hoop and longitudinal stresses, as well as equivalent stresses, presented in tabular form, in the area of the dent when exposed to the pipe by a bending load are obtained. The most loaded point in the area of the dent, which is located in the zone of the greatest depth of the defect, is determined.

Анализ данных мониторинга подземных трубопроводов показывает, что на внутренней поверхности трубы на пониженных участках профиля трассы происходит накопление водной фазы, вызванное расслоением эмульсии и конденсатом водяных паров. Цель исследования состоит в разработке эффективного способа защиты от коррозии внутренней поверхности подземного нефтепровода в условиях дифференциальной поляризации при расслоении водонефтяной эмульсии. Поставлены задачи по изучению развития коррозионного процесса на внутренней поверхности стенки трубы, имеющей контакт с пластовой водой и оценке принципиальной возможности использования гальванического покрытия для защиты от электрохимической коррозии. В процессе исследования применяли гравиметрический метод, прерывистый метод получения потенциостатических кривых, методы для определения рН среды, измерение разности электродных потенциалов. Показано, что возникновение разности потенциалов на поверхности металла, контактирующего с разными фазами водонефтяной эмульсии, способствует развитию гальванического элемента, причем анодный участок образуется на металлической поверхности, находящейся в пластовой воде. Взаимодействие стали 20 с цинком в пластовой воде способствует смещению электродного потенциала металла на 0,3 В в катодную область и достигает обратимых значений. В качестве метода защиты нефтепровода от внутренней коррозии рекомендовано анодное покрытие из цинка.

An analysis of underground pipeline monitoring data shows that aqueous phase accumulation occurs on the inner surface of the pipe on the lower sections of the route profile, caused by emulsion separation and water vapor condensation. The purpose of the study is to develop an effective method for protecting the inner surface of an underground oil pipeline against corrosion under conditions of differential polarization during the separation of an oil-water emulsion. The tasks were set to study the development of the corrosion process on the inner surface of the pipe wall, which is in contact with the produced formation water and to assess the fundamental possibility of using a galvanic coating to protect against electrochemical corrosion. It is shown that occurrence of potential difference on the surface of metal in contact with different phases of water-oil emulsion contributes to the development of galvanic cell, and the anode section is formed on metal surface in formation water. The interaction of steel (20) with zinc in formation water contributes to the displacement of the electrode potential of the metal by 0.3 V to the cathode area and reaches reversible values. Zinc anodic coating is recommended as a method of protecting of oil pipeline against internal corrosion.

Механическая и структурная неоднородность сварных соединений является следствием термодеформационного цикла сварки и в числе других факторов определяет сложное напряженно-деформированное состояние участков сварных швов. При этом существует необходимость совершенствования математической модели нагружения, учитывающей переменный угол наклона контактных плоскостей зон механической неоднородности и направление приложения внешней нагрузки. Авторами рассмотрен метод определения геометрии зон механической неоднородности сварных соединений и предложены аналитические инструменты, учитывающие влияние зон механической неоднородности на определение критической интенсивности напряжений для трещиноподобного дефекта. Сделан вывод о целесообразности количественного определения влияния механической неоднородности на несущую способность сварных соединений с трещиноподобным дефектом на основе комплексного подхода, базирующегося на результатах расчетов в рамках усовершенствованной математической модели, экспериментальных данных, а также численных методов, реализуемых специальными программными комплексами.

Mechanical and structural inhomogeneity of welded joints is a consequence of the thermal deformation cycle of welding and, among other factors, determines the complex stress-strain state of the sections of welded joints. At that there is a necessity to improve the mathematic loading model, which considers a variable inclination of contact planes of mechanical nonuniformity zones and direction of external load application. The paper considers a method for determining the complex shape of zones of mechanical heterogeneity of welded joints and possible analytical tools that consider the effect of zones of mechanical heterogeneity on determining the critical stress intensity and solving the Prandtl problem for a crack-like defect. It is concluded that it is advisable to quantitatively determine the effect of mechanical inhomogeneity on the bearing capacity of welded joints with a crack-like defect based on an integrated approach based on the results of calculations within the framework of an improved mathematical model, experimental data, as well as numerical methods implemented by special software methods.

Informasi yang berlebihan ini tidak hanya berisi konten yang valid namun juga misinformasi. Misinformasi ini semakin parah dengan adanya media sosial. Berbagai kerusakan sudah ditimbulkan oleh kesalahan informasi ini dari korban jiwa sampai pandemi yang berkepanjangan. Misinformasi semakin meningkat dengan penemuan vaksin COVID-19. Rendahnya angka vaksinasi di beberapa tempat membuat rencana eradikasi pandemi semakin sulit. Review ini merangkum kerusakan-kerusakan yang ditimbulkan oleh misinformasi dan juga saran-saran yang diberikan untuk mengatasi atau mengurangi misinformasi dalam pandemi di era digital.
PERANCANGAN SISTEM ANTISIPASI PADAM LISTRIK PADA AMPLIFIER MASJID BERBASIS ARDUINO UNO
Authors: Salam Rudi
Published: July 2022

Listrik merupakan suatu energi yang sangat berguna bagi kehidupan manusia. Sering terjadinya padam listrik di Indonesia, khusunya di Aceh mengakibatkan kesulitan dalam melakukan suatu kegiatan, misalnya dalam menjalankan peralatan-peralatan yang memiliki sumber energi dari listrik. Khusunya sound sistem atau amplifier, dimana alat tersebut dapat berguna sebagai pengeras suara pada saat melaksanakan suatu kegiatan misalnya pengeras suara di Masjid. Sensor LDR dapat mendeteksi terjadinya padam listrik pada indikator lampu pijar dengan sangat efisien. Baterai 12 volt yang digunakan hanya mampu mensuplay energi selama 50 menit saat sistem beroperasi sedangkan baterai 24 volt mampu mensuplay energi selama 2 jam pada saat sistem beroperasi pada kondisi padam listrik. Dimana baterai 12 volt hanya mampu mensuplay energi sangat minim karena pada saat pengisian baterai tidak terisi penuh. Dengan demikian diharapkan alat ini dapat berguna untuk mengatasi problema diatas dan meningkatan kekhusyukan dalam beribadah di Masjid.
PERANCANGAN ALAT PENGUKUR DEBIT AIR BERBASIS ARDUINO UNO SEBAGAI ANTISIPASI PEMBOROSAN AIR DI SEKTOR PERTANIAN
Authors: Yusuf Khaidir
Published: July 2022

Pada zaman ini berbagai jenis teknologi telah banyak dikembangkan oleh manusia untuk mempermudah pekerjaan. Alat ukur yang dulunya masih konvensional, sekarang sudah banyak menggunakan sistem digital. Untuk mengantisipasi pemborosan penggunaan air di sektor pertanian, dapat dilakukan dengan menggunakan alat ukur debit air, yang menggunakan water flow sensor dikombinasikan dengan sistem katup yang diputar oleh motor dc berbasis mikrokontroler arduino uno. Water flow sensor YF-S201 akan mendeteksi jumlah debit air yang mengalir. Arduino uno akan mengendalikan komunikasi dengan Water Flow Sensor yang dimulai dari mengirimkan perintah untuk meminta hasil pengukuran nilai debit air. Setelah itu, mengambil data tersebut kemudian mengolahnya dan mengirimkannya ke LCD sebagai tampilan hasil pengukuran debit air. Sensor air akan mendeteksi air pada suatu wadah apabila hampir terisi penuh, lalu memberikan sinyal yang berupa logika high dan low ke arduino uno untuk memutar motor dc agar sistem katup menutup. Perancangan alat  ini terdiri dari water flow sensor YF-S201, sensor air, motor dc mikrokontroler arduino UNO, dan sebuah LCD. Pada pengujian water flow sensor diperoleh nilai rata-rata volume air 5,6 L/M dan nilai rata-rata total 4,91 L. Tujuan akhir dari perancangan alat ini adalah untuk mengurangi pemborosan penggunaan air, dengan alat ukur yang dikombinasikan dengan sistem katup yang berupa motor dc untuk memutar keran air.

Published: July 2022

Vehicular Ad Hoc Network (VANET) or vehicle network is a technology developed for autonomous vehicles in Intelligent Transportation Systems (ITS). The communication system of VANET is using a wireless network that is potentially being attacked. The Sybil attack is one of the attacks that occur by broadcasting spurious information to the nodes in the network and could cause a crippled network. The Sybil strikes the network by camouflaging themselves as a node and providing false information to nearby nodes. This study is conducted to predict the Sybil attack by analyzing the attack pattern using a deep learning algorithm. The variables exerted in this research are time, location, and traffic density. By implementing a deep learning algorithm enacting the Sybil attack pattern and combining several variables, such as time, position, and traffic density, it reaches 94% of detected Sybil attacks.

Tomato is one of the agricultural products with the highest economic value in the world, for its production agrochemicals are generally used, however, their excessive use has caused environmental problems. A commercial sargassum extract was evaluated as a fertilizer for tomato cultivation, it was applied at 2 (N2), 5 (N5) and 8% (N8), with and without inoculation (400 spores) of arbuscular mycorrhizal fungi; mineral fertilization (C+) and no fertilization (C-) were used as controls. With C+ the highest number and weight of tomatoes were obtained, but the fruits were mostly small in diameter; with organic fertilization, medium-sized fruits were obtained, and they surpassed those of C- in all the parameters evaluated. The highest content of carotenoids was found in the tomatoes from N2, N5, N8 and NM8, the highest amount of sugar in the fruits from N5, N8 and NM8, the highest maturity and flavor indices in all organically fertilized with and without arbuscular mycorrhizal fungi except NM5. The use of sargassum as a fertilizer is a good alternative to avoid the problems caused by its excessive arrival on the coasts, and it is given added value since a biofertilizer is obtained that helps production and improves the quality of tomatoes.

A troca valvar para correção das valvopatias importantes deve ser indicada no momento correto da história natural da doença valvar para evitar as possíveis conse-quências irreversíveis. O substituto valvar ideal deve ter as seguintes características: ausência de ruído, boa durabilidade, ter fácil implante, ser composto por um tecido não trombogênico, não antigênico e que não precise anticoagulação permanente. Apesar de ainda não existir um substituto valvar com as características ideais, as próteses, biológicas ou mecânicas, evoluíram significativamente nas últimas décadas, em relação ao desenho, ao material utilizado, à forma de conservação e à técnica de implante, o que resultou em redução do risco de trombose da prótese e de fenômeno embólico, e menor necessidade de reoperação. Na escolha do substituto ideal, deve haver um equilíbrio entre o risco de trombose, o risco do sangramento e a necessidade de reope-ração, e deve sempre ser compartilhada com o paciente, levando em consideração fatores ligados ao paciente, à doença valvar e à prótese. Os pacientes com prótese valvar podem apresentar complicações relativas à disfunção secundária à degeneração estrutural, não estrutural, trombose e endocardite.
