Characterising Penetrometer Tip Contact during Concrete Condition Assessment
Authors: Hall Richard , Stumpf Alex , Baji Avinash , Ross Robert , Barnett Dean
Published: January 2022

Concrete condition-assessing penetrometers need to be able to distinguish between making contact with a hard (concrete) surface as opposed to a semi-solid (corroded concrete) surface. We investigated whether different shaped tips of a cylindrical penetrometer were better than others at maintaining contact with concrete and not slipping. We designed a range of simple symmetric tip shapes, controlled by a single superellipse parameter. We performed a finite element analysis of these parametric models in SolidWorks before machining in stainless steel. We tested our penetrometer tips on a concrete paver cut to four angles at 20∘ increments. The results indicate that the squircle-shaped tip had the least slippage when used for concrete condition assessment.

Published: January 2022

Image registration is an important basis of image processing, which is of great significance in image mosaicking, target recognition, and change detection. Aiming at the automatic registration problem of multi-angle optical images for ground scenes, a registration method combining point features and line features to register images is proposed. Firstly, the LSD (Line Segment Detector) algorithm is used to extract line features of images. The obtained line segments whose length are less than a given threshold are eliminated by a visual significant algorithm. Then, an affine transform model obtained by estimating a Gaussian mixture model (GMM) is applied to the image to be matched. Lastly, Harris point features are utilized in fine matching to overcome shortages of methods based on line features. In experiments, the proposed algorithm is compared with popular feature-based registration algorithms. The results indicate that the proposed algorithm in this work has obvious advantages in terms of registration accuracy and reliability for optical images acquired at different angles.

Published: January 2022

The paper considers the issues of creating high-temperature digital thermographs based on RGB photodetector arrays. It has been shown that increasing the reliability of temperature measurement of bodies with unknown spectral coefficient of thermal radiation can be ensured by optimal selection of the used spectral range and registration of the observed thermal radiation fields in three spectral ranges. The registration of thermal radiation in four or more spectral ranges was found to be inefficient due to the increasing error in temperature determination. This paper presents a method for forming three overlapping spectral regions in the NIR spectral range, which is based on the use of an external spectral filter and a combination of the spectral characteristics of an RGB photodetector array. It is shown that it is necessary to ensure the stability of the solution of the system of three nonlinear equations with respect to the influence of noise. For this purpose, the use of a priori information about the slope factor of the spectral dependence of the thermal radiation coefficient in the selected spectral range for the controlled bodies is proposed. The theoretical results are confirmed by examples of their application in a thermograph based on an array of CMOS RGB photodetectors.

Published: January 2022

The Fifth Generation (5G) mobile networks use millimeter waves (mmWaves) to offer gigabit data rates. However, unlike microwaves, mmWave links are prone to user and topographic dynamics. They easily get blocked and end up forming irregular cell patterns for 5G. This in turn causes too early, too late, or wrong handoffs (HOs). To mitigate HO challenges, sustain connectivity, and avert unnecessary HO, we propose an HO scheme based on a jump Markov linear system (JMLS) and deep reinforcement learning (DRL). JMLS is widely known to account for abrupt changes in system dynamics. DRL likewise emerges as an artificial intelligence technique for learning highly dimensional and time-varying behaviors. We combine the two techniques to account for time-varying, abrupt, and irregular changes in mmWave link behavior by predicting likely deterioration patterns of target links. The prediction is optimized by meta training techniques that also reduce training sample size. Thus, the JMLS–DRL platform formulates intelligent and versatile HO policies for 5G. When compared to a signal and interference noise ratio (SINR) and DRL-based HO scheme, our HO scheme becomes more reliable in selecting reliable target links. In particular, our proposed scheme is able to reduce wasteful HO to less than 5% within 200 training episodes compared to the DRL-based HO scheme that needs more than 200 training episodes to get to less than 5%. It supports longer dew time between HOs and high sum rates by ably averting unnecessary HOs with almost half the HOs compared to a DRL-based HO scheme.

Published: January 2022

Machine Learning (ML)-based methods have been identified as capable of providing up to one day ahead Photovoltaic (PV) power forecasts. In this research, we introduce a generic physical model of a PV system into ML predictors to forecast from one to three days ahead. The only requirement is a basic dataset including power, wind speed and air temperature measurements. Then, these are recombined into physics informed metrics able to capture the operational point of the PV. In this way, the models learn about the physical relationships of the different features, effectively easing training. In order to generalise the results, we also present a methodology evaluating this physics informed approach. We present a study-case of a PV system in Denmark to validate our claims by extensively evaluating five different ML methods: Random Forest, Support Vector Machine, Convolutional Neural Networks (CNN), Long-Short Term Memory (LSTM) and a hybrid CNN–LSTM. The results show consistently how the best predictors use the proposed physics-informed features disregarding the particular ML-method, and forecasting horizon. However, also, how there is a threshold regarding the number of previous samples to be included that appears as a convex function.
SARS-CoV-2 Detection Using Optical Fiber Based Sensor Method
Authors: Hadi Muhammad Usman , Khurshid Menal
Published: January 2022

The SARS-CoV-2 Coronavirus disease, also known as the COVID-19 pandemic, has engendered the biggest challenge to human life for the last two years. With a rapid increase in the spread of the Omicron variant across the world, and to contain the spread of COVID-19 in general, it is crucial to rapidly identify this viral infection with minimal logistics. To achieve this, a novel plastic optical fiber (POF) U-shaped probe sensing method is presented for accurate detection of SARS-CoV-2, commonly known as the COVID-19 virus, which has the capability to detect new variants such as Omicron. The sample under test can be taken from oropharyngeal or nasopharyngeal via specific POF U-shaped probe with one end that is fed with a laser source while the other end is connected to a photodetector to receive the response and postprocess for decision-making. The study includes detection comparison with two types of POF with diameters of 200 and 500 µm. Results show that detection is better when a smaller-diameter POF is used. It is also seen that the proposed test bed and its envisaged prototype can detect the COVID-19 variants within 15 min of the test. The proposed approach will make the clinical diagnosis faster, cheaper and applicable to patients in remote areas where there are no hospitals or clinical laboratories due to poverty, geographic obstacles, or other factors.
Uncertainties in Atomic Data for Modeling Astrophysical Charge Exchange Plasmas
Authors: Gu Liyi , Shah Chintan , Zhang Ruitian
Published: January 2022

Relevant uncertainties of theoretical atomic data are vital to determining the accuracy of plasma diagnostics in a number of areas, including, in particular, the astrophysical study. We present a new calculation of the uncertainties on the present theoretical ion-impact charge exchange atomic data and X-ray spectra, based on a set of comparisons with the existing laboratory data obtained in historical merged-beam, cold-target recoil-ion momentum spectroscopy, and electron beam ion traps experiments. The average systematic uncertainties are found to be 35–88% on the total cross sections, and 57–75% on the characteristic line ratios. The model deviation increases as the collision energy decreases. The errors on total cross sections further induce a significant uncertainty to the calculation of ionization balance for low-temperature collisional plasmas. Substantial improvements of the atomic database and dedicated laboratory measurements are needed to obtain the current models, ready for the X-ray spectra from the next X-ray spectroscopic mission.

Semantically rich data coming from hyperspectral sensors are a prerequisite for the timely and rational implementation of plant protection measures. This review presents modern advances in early plant disease detection based on hyperspectral remote sensing. The review identifies current gaps in the methodologies of experiments. A further direction for experimental methodological development is indicated. A comparative study of the existing results is performed and a systematic table of different plants’ disease detection by hyperspectral remote sensing is presented, including important wave bands and sensor model information.
Characterization of Open-Ended Coaxial Probe Sensing Depth with Respect to Aperture Size for Dielectric Property Measurement of Heterogeneous Tissues
Authors: Aydinalp Cemanur , Joof Sulayman , Dilman Ismail , Akduman Ibrahim , Yilmaz Tuba
Published: January 2022

The open-ended coaxial probe (OECP) method is frequently used for the microwave dielectric property (DP) characterization of high permittivity and conductivity materials due to inherent advantages including minimal sample preparation requirements and broadband measurement capabilities. However, the OECP method is known to suffer from high measurement error. One well-known contributor to the high error rates is tissue heterogeneity, which can potentially be managed through the selection of a probe with a proper sensing depth (SD). The SD of the OECP is dependent on many factors including sample DPs and probe aperture diameter. Although the effects of sample DPs on SD have been investigated to some extent in the literature, the probe aperture diameters, particularly small diameters, have not been fully explored. To this end, the SDs of probes with three different apertures (0.5, 0.9 and 2.2 mm-diameters) were analyzed in this study. Probes’ SDs were first investigated with simulations using a double-layered sample configuration (skin tissue and olive oil). Next, experiments were performed using a commercial OECP with a 2.2 mm aperture diameter. The SD was categorized based on 5%, 20% and 80% DP change. Among these threshold values, a 5% DP change was selected as the benchmark for SD categorization. The findings suggest that probes with a smaller aperture size and correspondingly smaller SD should be utilized when measuring the DPs of thin and multilayered samples, such as healthy and diseased skin tissues, to increase the measurement accuracy.

Published: January 2022

Due to the increasing need for a more sustainable environment, the study of waste management strategies is increasing worldwide. Pneumatic urban waste collection is an alternative to the conventional truck collection, especially in urban areas, where there is a need of reducing traffic and its pollution. LCA is a methodology that can help in the evaluation of the environmental impact of any process or product; therefore, this study, based on the methodologies ISO 14040 and from the cradle to the grave, compares different waste collection systems in an airport. The results show that the pneumatic collection system with the innovative AutoWaste compact central unit can reduce the annual flow of greenhouse gases into the atmosphere (kilograms of carbon dioxide equivalent for 30 years and per ton) up to 25% compared to a pneumatic collection system with a conventional central.

Authors: Wang I-Lin , Li Yu-Ge , Su Yu , Yao Shun , Zhang Ke-Ke , Chen Che-Hsiu , Wang Shin-Yuan
Published: January 2022

Background: The study explored the influence of repeated drop jumps (DJs) from different drop heights on the lower extremity bilateral asymmetry and muscle activation of countermovement jumps (CMJs). Methods: Eighteen male athletes performed 200 drop jumps (DJs200) from three drop jump height (DJH30, 40 and 50 cm). The CMJs were performed before the first DJ and after the 50th, 100th, 150th and 200th DJs, recording them as pre-CMJ, CMJs50, CMJs100, CMJs150 and CMJs200. One-way repeated measures ANOVA was used to compare differences among the three drop heights at pre-CMJ, CMJs50, CMJs100, CMJs150 and CMJs200, respectively. Results: The peak ground reaction forces (PGRF) of CMJs100, CMJs150 and CMJs200 at DJH50 were greater than at DJH30 and DJH40 (all p < 0.05). The muscle activation during CMJs50 at DJH50 was greater than at DJH30 and DJH40 (all p < 0.05). The muscle activation during CMJs100, CMJs150 and CMJs200 at DJH50 was smaller than at DJH40 and DJH30 (all p < 0.05). The PGRF had no significant difference among the three different drop heights during CMJs50 (p > 0.05). Conclusions: The DJs50 at DJH50 had no effect on the bilateral asymmetry and increased muscle activation of CMJs. The excessive DJs100 at DJH50 increased bilateral asymmetry and decreased CMJ muscle activation during CMJs.

Published: January 2022

Shiga toxin-producing Escherichia coli (STEC) causes proximal tubular defects in the kidney. However, factors altered by Shiga toxin (Stx) within the proximal tubules are yet to be shown. We determined Stx receptor Gb3 in murine and human kidneys and confirmed the receptor expression in the proximal tubules. Stx2-injected mouse kidney tissues and Stx2-treated human primary renal proximal tubular epithelial cell (RPTEC) were collected and microarray analysis was performed. We compared murine kidney and RPTEC arrays and selected common 58 genes that are differentially expressed vs. control (0 h, no toxin-treated). We found that the most highly expressed gene was GDF15, which may be involved in Stx2-induced weight loss. Genes associated with previously reported Stx2 activities such as src kinase Yes phosphorylation pathway activation, unfolded protein response (UPR) and ribotoxic stress response (RSR) showed differential expressions. Moreover, circadian clock genes were differentially expressed, suggesting Stx2-induced renal circadian rhythm disturbance. Circadian rhythm-regulated proximal tubular Na+-glucose transporter SGLT1 (SLC5A1) was down-regulated, indicating proximal tubular functional deterioration, and mice developed glucosuria confirming proximal tubular dysfunction. Stx2 alters gene expression in murine and human proximal tubules through known activities and newly investigated circadian rhythm disturbance, which may result in proximal tubular dysfunctions.
Alphacoronaviruses Are Common in Bats in the Upper Midwestern United States
Authors: Schaeffer Reagan , Temeeyasen Gun , Hause Ben M.
Published: January 2022

Bats are a reservoir for coronaviruses (CoVs) that periodically spill over to humans, as evidenced by severe acute respiratory syndrome coronavirus (SARS-CoV) and SARS-CoV-2. A collection of 174 bat samples originating from South Dakota, Minnesota, Iowa, and Nebraska submitted for rabies virus testing due to human exposure were analyzed using a pan-coronavirus PCR. A previously partially characterized CoV, Eptesicus bat CoV, was identified in 12 (6.9%) samples by nested RT-PCR. Six near-complete genomes were determined. Genetic analysis found a high similarity between all CoV-positive samples, Rocky Mountain bat CoV 65 and alphacoronavirus HCQD-2020 recently identified in South Korea. Phylogenetic analysis of genome sequences showed EbCoV is closely related to bat CoV HKU2 and swine acute diarrhea syndrome CoV; however, topological incongruences were noted for the spike gene that was more closely related to porcine epidemic diarrhea virus. Similar to some alphaCoVs, a novel gene, ORF7, was discovered downstream of the nucleocapsid, whose protein lacked similarity to known proteins. The widespread circulation of EbCoV with similarities to bat viruses that have spilled over to swine warrants further surveillance.
Integrated Watershed Management Framework and Groundwater Resources in Africa—A Review of West Africa Sub-Region
Authors: Tang Xiaolan , Adesina John Adekunle
Published: January 2022

Human activities mostly impact the trend and direction of rainwater, groundwater, and other river basin resources in the watershed in Africa. These activities alter river flows and the quality of usable water supplies at both highlands and lowlands. A watershed is indeed a conserved area of land that collects rain, sleet and snow, and empties or penetrates groundwater sources. The act of managing the activities around the watershed is integrated watershed management, which considers the social, economic, and environmental issues in tandem with the human, institutional, natural, and sustainability systems, which are the key drivers as identified in this study, as well as community interests and participation, to manage groundwater resources sustainably. These watersheds, river basins, and groundwater resources provide important services for communities and biodiversity. This paper reveals that the best way to protect groundwater resources is on a watershed basis using sustainable management measures. This technique enables us to handle a variety of concerns and objectives while also allowing us to plan in a complicated and uncertain environment. Sustaining a regional and sub-regional watershed involves cooperation and participation from a wide range of community interests and water users, including municipalities, companies, people, agencies, and landowners, for stakeholders’ input to be successful. All of the strategies and plans are produced with regard to one another, as well as the overall conditions of the watershed, local land uses, and specific regional transboundary issues.

Published: January 2022

Flood Frequency Analysis (FFA) and the non-stationary FFA approaches are used in flood study, water resource planning, and the design of hydraulic structures. However, there is still a need to develop these methods and to find new procedures that can be used in estimating simple distributions in controlled catchments. The aim of the study is a comparison of three-parameter distributions in controlled catchments for stationary and non-stationary data series and further to develop the procedure of the estimation the simple distributions. Ten rivers from the Czech Republic and Poland were selected because of their existing or planned reservoirs as well as for flood protection reasons. The annual maximum method and the three-parameter Weibull, Log-Normal, Generalized extreme value, and Pearson Type III distributions were used in this study. The analyzed time series are stationary and non-stationary. The methodology used in this study, which makes use of the Maximum Likelihood Estimation, allows one to simplify the analysis whenever there is a series of data that is both stationary and non-stationary. The novelty in our research is the standardization and development of a new procedure for a stationary and non-stationary data series, taking into account to read a specific value of the maximum flow with a given exceedance probability from the lower or upper tail. It determines the optimal choice of the theoretical distribution that can be used, for example in the design of weirs in rural areas (lower quantiles) or in the design of hydrotechnical structures in areas at risk of flooding (upper quantiles).
Assessment of the Usability of SAR and Optical Satellite Data for Monitoring Spatio-Temporal Changes in Surface Water: Bodrog River Case Study

Published: January 2022

Mapping watercourses and their surroundings through remote sensing methods is a fast, continuous, and effective method and is a crucial tool for capturing change and possibly predicting hazards. Thanks to Synthetic Aperture Radar (SAR) technology and the ability of its backscattered and emitted radiation to penetrate the atmosphere under any conditions, this type of mapping of water surfaces is of particular importance. This paper presents the possibility of using SAR technology for long-term observations of changes in the behaviour of rivers and river systems, combined with optical multispectral images Sentinel-2. Additionally, it aims to demonstrate the suitability of satellite SAR and multispectral data implementation for mapping changes in watercourses, caused not only by their natural development but especially by inundation processes in their catchment area. Appropriate Sentinel-1 image processing evaluation procedures demonstrate that the usage of vertical-vertical (VV) type polarisation configuration is a suitable methodology for documenting water bodies, and a Lee filter is an acceptable tool for radar noise filtering. The extraction process of water surfaces is based on the determination of threshold values using the “Otsu” principle. Subsequently, the comparison of the results is realised by the spectral indices of water—the Normalized Difference Water Index (NDWI), Modified Normalized Difference Water Index (MNDWI), a pair of Automated Water Extraction Index (AWEI) indices, and supervised classification method Maximum Likelihood Classification (MLC). The results are numerical and graphical evaluated. In assessing the accuracy of SAR extraction, the highest values achieved in Overall Accuracy (OA) were a maximum of 98.6%. On average, the lower values were in User Accuracy (UA) with a maximum of 93.1%, where VV polarisation also dominates. However, vertical-horizontal (VH) polarisation dominates in Producer Accuracy (PA) with a maximum of 84.9%.

Published: January 2022

This article proposes the method of economic evaluation of agricultural lands with linear objects and corresponding protection zones on the example of agricultural enterprise in the Arkadak district, Saratov region through the formation of land information system and evaluation of land plots using income and comparative approaches. As a result of the study, the land information system of the economy was compiled, the main indicators of the studied land plots were collected and the qualitative (taking into account current legislation regarding these zones) and the quantitative impact of zones with a special regime of land use on the value of agricultural land on the basis of income and comparative approaches was established in this work. Zones with a special regime of land use reduce market value of lands by changing the contour score of the land plot, which in turn creates complexity and increases cultivation costs. Within the framework of the comparative approach, it is proposed to apply adjustments for the configuration complexity. The proposed investigations will find application in assessing the market value of agricultural land plots with a special regime of land use.

Eucalyptus globulus essential oil increases neovascularization and vascular endothelial growth factor expression in male Wistar rats exposed to UVB
Authors: Indrawati Noviana , Iswari Ida Sri , Winarti Ni Wayan
Published: January 2022

Background

Eucalyptus globulus essential oil contained 1,8-cineol, which may accelerate wound healing. This study aimed to prove Eucalyptus globulus essential oil’s effect on increasing neovascularization and Vascular Endothelial Growth Factor (VEGF) expression in Wistar rats skin exposed to ultraviolet B (UVB).

Methods

A Post-test only controls group study design was applied on 36 male Wistar rats, aged 3-4 months old, weighing 150-200 grams. The animal subject was exposed to UVB (65 mJ/cm2, 65 seconds for seven days), injured on their back using a punch biopsy with a diameter of 10 mm, and divided into two groups. For seven days, on the wound, the control group was given 2 ml of 0.9% NaCl twice a day, while the treatment group was given Eucalyptus globulus essential oil (2 ml). Both groups were given oral Amoxicillin three times a day. The skin tissue was taken on day eight to assess neovascularization and VEGF expression.

Results

The results show that neovascularization in the treatment group was higher than in the control group (p < 0.05). Meanwhile, the median VEGF expression in the treatment group was also higher than in the control group (p < 0.05).

Conclusions

Topical administration of Eucalyptus globulus essential oil increased neovascularization and VEGF expression in the skin of male Wistar rats injured and exposed to UVB. Further research is needed to assess the effectiveness of the essential oil in enhancing neovascularization and VEGF expression in humans with multiple exposures at different doses to optimize the wound-healing effect.

Ontological principles and genesis of virtual assets (cryptocurrencies) in modern conditions of development of social and legal system
Authors: Shkolnyi Vladyslav
Published: January 2022

The article considers the principles of the emergence of virtual assets (cryptocurrencies) and the impact on these events of economic, socio-political relations through technological features. The paper considers the influence of the Austrian School of Economics and its achievements on the emergence and development of modern virtual assets, namely they considered the impact on the choice of available currencies: 1) as the purchase of goods and services, 2) as a reserve for future needs; 3) as deferred payments; 4) as a unit of account. According to Hayek's theoretical framework, market forces will determine the relative values of different competing currencies. As a result, exchange rates between competing currencies will float freely.

Salah satu masalah penting dari demokrasi daerah adalah politik kekerabatan. 124 calon kepala daerah pada pemilihan umum kepala daerah 2020 di Indonesia terpapar politik kekerabatan. Demokrasi sebagai sistem yang memposisikan rakyat pemegang kedaulatan telah kehilangan ruhnya. Ditemukan sepuluh faktor dominan penyebab terjadinya insecurisme politik rakyat; rendahnya kesadaran politik rakyat, minimnya edukasi politik kepada rakyat, partisipasi politik rakyat bersifat passif, pragmatisme partai politik pada kandidasi calon kepala daerah, ketidakpercayaan rakyat terhadap calon kepala daerah, lemahnya sosialisasi KPU terhadap rakyat tentang pentingnya penggunaan suara dalam menentukan kondisi daerah,Â  pemutakhiran data pemilih, tingginya modus transaksi calon kepala daerah kepada rakyat, formalitas ketentuan calon kepala daerah, dan kran politik kekerabatan dibuka secara leluasa melalui Undang-Undang Nomor 6 Tahun 2020 tentang tentang Pemilihan Gubernur, Bupati, dan Walikota. Kemudian sepuluh faktor tersebut membentuk insecurisme politik rakyat Indonesia. Rakyat memposisikan dirinya tidak berdaya dan beranggapan tidak memiliki pengaruh dalam demokrasi sehingga melakukan pembiaran atas maraknya politik kekerabatan.

STRUCTURE OF THE CONCEPT “DRAGON / 龙 LÓNG” IN CHINESE LINGUOCULTURE
Authors: Пляскина Екатерина Андреевна
Published: January 2022

В статье предпринимается попытка построения структуры китайского лингвокультурного концепта «дракон / A long». Несмотря на то что китайский дракон является объектом многих исследований, опыт построения структуры данного концепта отсутствует. В работе применяется методика анализа концептуальной структуры М. В. Пименовой. В статье используются описательный метод, метод концептуального анализа, метод компонентного анализа, метод анализа словарных дефиниций. Наиболее полно национально-культурное своеобразие концепта раскрывается при обращении к языковым данным, поэтому материалом исследования стали фразеологические и лексические единицы китайского языка, репрезентирующие рассматриваемый концепт. В статье выявляются основные мотивирующие, образные, понятийные, архаичные понятийные, функциональные, ценностно-оценочные и символические признаки, составляющие структуру концепта «дракон / A long». Выясняется, что концепт «дракон / A long» обладает слоистой структурой, которая включает множество временных напластований значений. При этом ядро концепта остается, как правило, условно-неизменной константой. Особенностью рассматриваемого концепта является наличие у него символических признаков - важного показателя его значимости для лингвокультуры. Именно данная группа признаков наиболее ярко отражает национальную специфику рассматриваемого концепта, поскольку лишь в Китае он приобрел подобную значимость, став символом целой нации.

This article attempts to construct a structure of the Chinese linguocultural concept “dragon / A long”. Despite the fact that Chinese dragon is an object of many research works there is no attempt to construct this concept structure. The study employs the methods of conceptual structure analysis by M. V. Pimenova. Other methods employed are the method of conceptual analysis, component analysis and analysis of vocabulary definitions. The appeal to language facts helps to the most complete disclosure of national and cultural singularity of the concept. Therefore, the material of study is phraseological and lexical units which represent the concept under consideration. The article identifies the main features forming the structure of the concept “dragon / A long”. They are motivating, figurative, conceptual, archaic conceptual, value-estimate, and symbolic features. It turned out that the concept “dragon / A long” has a complex structure including many layers. However, the core of the concept remains the same. The specificity of the considered concept is that it has symbolic features. It is an important indicator of concept significance for the linguoculture. These features express national specificity of the concept achieving such importance only in China and becoming a symbol of the whole nation.

Authors: Парфенова Ольга Васильевна , Николаева Анастасия Вячеславовна
Published: January 2022

В статье представлены результаты изучения проблемы ранней технической профориентации детей старшего дошкольного возраста посредством профессиоведения. Авторы на основе анализа нормативных документов, теоретических работ и практического опыта раскрывают актуальность ранней профориентации и необходимость ознакомления детей дошкольного возраста с технической сферой жизни человека. Интерес к данной сфере обусловлен реализацией важной задачи государства по подготовке высококвалифицированных инженерно-технических кадров для промышленной сферы, интеллектуально развитых, способных к результативной технической деятельности. Результаты беседы с детьми старшего дошкольного возраста о технических профессиях показали, что большинство дошкольников имеют низкий уровень представлений о технических профессиях: дети затрудняются в назывании технических профессий, не могут описать трудовые действия, перечислить инструменты, оборудование и технику, индифферентны к техническим профессиям. Авторы обосновывают необходимость использования в процессе ранней технической профориентации профессиоведческого подхода, позволяющего определить необходимые для освоения детьми старшего дошкольного возраста знания о конкретных технических профессиях, а также подчеркивают важность сочетания методов информирования (рассказ, беседа, просмотр иллюстративных материалов, проектная деятельность и т. п.) и профессионального моделирования (сюжетно-ролевая игра).

The article presents the results of studying the problem of early technical career guidance among senior preschoolers through vocational studies. The authors, basing on the analysis of normative documents, theoretical works and practical experience, reveal the relevance of early career guidance and the need to familiarize preschool children with the technical sphere of human life. The interest in this area is due to the implementation of an important task of the state to train highly qualified engineering and technical personnel that are to be intellectually developed, capable of effective technical activities, for the industrial sector. The results of the conversation with senior preschool children about technical professions showed that most preschoolers hardly have any idea about technical professions: children find it difficult to name any technical professions, they cannot name labor actions or list any tools, equipment and machinery, and they are rather indifferent to technical professions. The authors substantiate the need to use a profession-based approach in the process of early technical career guidance. This approach allows us to determine the content of knowledge about specific technical professions necessary for the development of senior preschool children. They note the need for a combination of information methods (story, conversation, viewing illustrative materials, project activities, etc.) and professional modeling (story-role-playing) in the process of early technical career guidance for senior preschool children.
