Published: June 2024

Ewing sarcoma is the second most common bone cancer in children, and while patients who present with metastatic disease at the time of diagnosis have a dismal prognosis. Ewing sarcoma tumors are driven by the fusion gene EWS/Fli1, and while these tumors are genetically homogenous, the transcriptional heterogeneity can lead to a variety of cellular processes including metastasis. In this study, we demonstrate that in Ewing sarcoma cells, the canonical Wnt/β-Catenin signaling pathway is heterogeneously activated in vitro and in vivo, correlating with hypoxia and EWS/Fli1 activity. Ewing sarcoma cells predominantly express β-Catenin on the cell membrane bound to CDH11, which can respond to exogenous Wnt ligands leading to the immediate activation of Wnt/β-Catenin signaling within a tumor. Knockdown of CDH11 leads to delayed and decreased response to exogenous Wnt ligand stimulation, and ultimately decreased metastatic propensity. Our findings strongly indicate that CDH11 is a key component of regulating Wnt//β-Catenin signaling heterogeneity within Ewing sarcoma tumors, and is a promising molecular target to alter Wnt//β-Catenin signaling in Ewing sarcoma patients.

Photographs as layered objects in Oceania
Authors: Waldroup Heather
Published: June 2024

Historical photographs from the Pacific were often produced by white photographers, but they nevertheless serve as records of historical and cultural significance to Indigenous communities today. Although scholarship on photography from the Pacific has increased since the 1990s, the field has not entirely kept up with broader critical discussions in visual studies and Pacific Islands studies. This article takes a material approach to photographs, arguing for them (in spite of their flatness) as layered objects, much in the way taonga, or precious heirlooms, might be conserved and displayed through wrapping, binding and layering. The discussion focuses on two photo-based images: an ambrotype of a Tongan missionary, Barnabas ‘Ahongalu, created in Fiji in the 1860s and a pastel painting based on a family photograph by contemporary Native Hawaiian artist Michele Zalopany. By considering the multiple and layered histories present in these images, this article departs from an approach to photographs from Oceania as solely products of settler-colonialist and imperial desires. Instead, it seeks to engender new directions in conversations about photographs and photography that centre Indigenous experiences and histories.

Published: June 2024

The article offers an up-to-date interpretation of the concept ‘personnel career advancement factors’. It also defines different approaches to the distribution of factors that greatly affect the career growth of personnel in educational institutions. The analysis of the factors of personnel career advancement in the educational institution is proposed to be carried out according to the developed step-by-step scheme of analysis of factors that have the greatest impact on the career advancement of employees in educational institutions. It is suggested to use cluster and discriminant analysis to establish the regularities of the relationship between these factors and to determine the relevant factors. To construct discriminant functions, the method of step-by-step inclusion is used, which involves the step-by-step addition of various combinations of factors to the calculations. As a result, a model has been developed that reflects the relationship between the factors that have the greatest impact on the career growth of employees in the educational institution. With the help of cluster analysis, the factors that influence the career growth of personnel in the educational institution are determined and, accordingly, clusters are built.
Keywords: factors, career advancement, personnel, educational institutions, discriminant analysis, cluster analysis.
"The Norm Culture" advocates for the introduction of a security layer in continuously learning AI models to protect against data and label poisoning attacks
Authors: Dahman Deniz
Published: June 2024

This paper presents a method to protect learning AI models against data and label poisoning attacks; The Norm Culture method posits that each class in an image classification problem possesses an inherent structure that serves as a primary defense against attacks—such as data or label poisoning—that can corrupt new training and testing samples during the parameter update phase of an AI predictive model within a conventional deep learning framework. The method requires calculating three elements from the essential training and testing samples. The first element is the flattened matrix representing the class image. The second element is the class alpha, a scalar that represents the weight norm of the class. The final element is the most recently validated AI predictive model. The experimental outcomes on a binary class image classification dataset from health domains indicate that the proposed method effectively identifies training and testing sample images compromised by either type of attack one or two. Additionally, there is potential for enhancing the method within the mathematical functions of the AI framework

Authors: Shrestha Swati , Ojha Grishma , Sharma Gourav , Mainali Raju , Galvin Liberty
Published: June 2024

Wheat is a staple grain crop in the United States and around the world. Weed infestation, particularly grass weeds, poses significant challenges to wheat production, competing for resources and reducing grain yield and quality. Effective weed management practices, including early identification and targeted herbicide application are essential to avoid economic losses. Recent advancements in unmanned aerial vehicles (UAVs) and artificial intelligence (AI), offer promising solutions for early weed detection and management, improving efficiency and reducing negative environment impact. The integration of robotics and information technology has enabled the development of automated weed detection systems, reducing the reliance on manual scouting and intervention. Various sensors in conjunction with proximal and remote sensing techniques have the capability to capture detailed information about crop and weed characteristics. Additionally, multi-spectral and hyperspectral sensors have proven highly effective in weed vs crop detection, enabling early intervention and precise weed management. The data from various sensors consecutively processed with the help of machine learning and deep learning models (DL), notably Convolutional Neural Networks (CNNs) method have shown superior performance in handling large datasets, extracting intricate features, and achieving high accuracy in weed classification at various growth stages in numerous crops. However, the application of deep learning models in grass weed detection for wheat crops remains underexplored, presenting an opportunity for further research and innovation. In this review we underscore the potential of automated grass weed detection systems in enhancing weed management practices in wheat cropping systems. Future research should focus on refining existing techniques, comparing ML and DL models for accuracy and efficiency, and integrating UAV-based mapping with AI algorithms for proactive weed control strategies. By harnessing the power of AI and machine learning, automated weed detection holds the key to sustainable and efficient weed management in wheat cropping systems.

Authors: Murniarti Erni , Sihotang Hotmaulina
Published: June 2024

This study aims to investigate the effect of digital literacy and self-efficacy on the commitment of the teaching profession at the Pangudi Luhur Foundation Jakarta. Teachers have an important role in educating, guiding, and assessing learners at various levels of education. The teacher qualification standards stipulated by Law No. 14/2005 emphasize the importance of pedagogic, personality, social, and professional competencies in carrying out their duties. The commitment of the teaching profession greatly affects the effectiveness of the learning process, while digital literacy and self-efficacy are internal factors that influence this commitment. The research method used was quantitative using Likert scale questionnaires. The research sample consisted of 104 teachers at Yayasan Pangudi Luhur Jakarta. The results showed that digital literacy had a positive and significant influence on the commitment of the teaching profession, with a regression of 0.909 and a determination of variance of 0.827. Similarly, teacher self-efficacy also had a significant influence on professional commitment, with a regression of 0.828 and a determination of variance of 0.686. However, when digital literacy and self-efficacy were considered together, the effect became stronger with a regression of 0.926 and a determination of variance of 0.858. These findings provide important implications for education practitioners, school principals, and educational foundations in developing strategies to increase the commitment of the teaching profession. Suggestions include organizing workshops and seminars to improve teachers' digital literacy and self-efficacy, as well as support from school principals and foundations in this regard. Thus, this research makes a significant contribution in understanding the factors that influence the commitment of the teaching profession and provides a foundation for the development of more effective education in the future.

Published: June 2024

Studying acute changes in vascular endothelial cells in humans is challenging. We studied ten African American women and used the J‐wire technique to isolate vein endothelial cells before and after a four‐hour lipid and heparin infusion. Dynamic changes in lipid‐induced oxidative stress and inflammatory markers were measured with fluorescence‐activated cell sorting. We used the surface markers CD31 and CD144 to identify human endothelial cells. Peripheral blood mononuclear cells isolated from blood were used as a negative control. The participants received galantamine (16 mg/day) for 3 months. We previously demonstrated that galantamine treatment effectively suppresses lipid‐induced oxidative stress and inflammation. In this study, we infused lipids to evaluate its potential to increase the activation of endothelial cells, as assessed by the levels of CD54+ endothelial cells and expression of Growth arrest‐specific 6 compared to the baseline sample. Further, we aimed to investigate whether lipid infusion led to increased expression of the oxidative stress markers IsoLGs and nitrotyrosine in endothelial cells. This approach will expedite the in vivo identification of novel pathways linked with endothelial cell dysfunction induced by oxidative stress and inflammatory cytokines. This study describes an innovative method to harvest and study human endothelial cells and demonstrates the dynamic changes in oxidative stress and inflammatory markers release induced by lipid infusion.
Validation of basal metabolic rate equations in persons with innervated and denervated chronic spinal cord injury
Authors: Alazzam Ahmad M. , Gorgey Ashraf S.
Published: June 2024

Basal metabolic rate (BMR) measurement is time consuming and requires specialized equipment. Prediction equations allow clinicians and researchers to estimate BMR; however, their accuracy may vary across individuals with chronic spinal cord injury (SCI). The objective of this study was to investigate the validity of SCI‐specific equations as well as able‐bodied (AB) prediction equations in individuals with upper motor neuron (UMN), lower motor neuron (LMN), and females with SCI. Twenty‐six men and women with chronic SCI (n = 12 innervated males, n = 6 innervated females, n = 8 denervated males) participated in this cross‐sectional study. BMR values were measured by indirect calorimetry. Body composition (dual‐energy X‐ray absorptiometry and anthropometrics) assessment was conducted. AB‐prediction equations [Cunningham, Nelson, Owen, Harris and Benedict, Mifflin, Schofield, Henry] and SCI‐specific equations [Chun and Nightingale & Gorgey] were used to estimate and validate BMR. The accuracy of AB‐specific FFM equations in predicting BMR was evaluated using Bland–Altman plots, paired t‐tests, and error metrics. Measured BMR for innervated males, females, and denervated males was 1436 ± 213 kcal/day, 1290 ± 114, and 1597 ± 333 kcal/day, respectively. SCI‐specific equations by Chun et al., Nightingale & Gorgey, and AB‐specific FFM equations accurately predicted BMR for innervated males. For the denervated males, Model 4 equation by Nightingale & Gorgey was not different (p = 0.18), and Bland–Altman analyses showed negative mean bias but similar limits of agreement between measured and predicted BMR for the SCI‐specific equations and AB‐specific FFM equations. We demonstrated that SCI‐specific equations accurately predicted BMR for innervated males but underpredicted it for denervated males. The Model 4 equation by Nightingale & Gorgey accurately estimated BMR in females with SCI. Findings from the current study will help to determine caloric needs in different sub‐groups of SCI.

Published: June 2024

Due to the environmental problems linked to the production of portland cement, the search for new more economic and non-polluting construction materials has become a current issue of interest. Geopolymers represent new types of “polymeric” materials of mineral nature. The aim of this work is to study the influence of the Na2SiO3/NaOH mass ratio and curing time on the mechanical and microstructural properties of fly-ash-based geopolymers GP-Fs. The samples were synthesized with different Na2SiO3/NaOH mass ratios (2.5, 4, and 6) and curing times (2, 12, and 24 h) at 60°C. The GP-F pastes elaborated were analyzed by scanning electron microscopy, Fourier transform infrared (FTIR) spectroscopy, and X-ray diffraction (XRD). The sample with the highest compressive strength and density and the lowest water absorption was produced with a Na2SiO3/NaOH mass ratio of 2.5 and a curing time of 24 h, which is GP1, as confirmed by FTIR and XRD analyses; in addition, it had a compact structure attributed to a higher pozzolanic reactivity. These optimized geopolymer pastes were studied to assess the durability test, evaluating the resistance to fire and acid attack. Fire resistance was assessed by heating the GP-F pastes to 800°C for 2 h, and acid resistance was studied by immersing specimens in a solution of 6% acetic acid (GP-F-CH3COOH) and 6% hydrochloric acid (GP-F-HCl) for 2 months. Physico-chemical and microstructural changes before and after heat and acid exposure were studied using several analyses. Samples exposed to an acidic environment display a completely porous shape with some micro-cracks, inducing a decrease of the residual compressive energy. FTIR analysis showed that the geopolymer gel deformed after heating to 800°C, and pores were formed in their structure due to evaporation of water.
TOC prediction of source rocks based on the convolutional neural network and logging curves – A case study of Pinghu Formation in Xihu Sag
Authors: Jingwen Yan , Wenxiang He , Xiaoyang Gao , Yong Hu
Published: June 2024

The total organic carbon (TOC) content is an important index for source rock evaluation. However, due to the scarcity of rock samples, the vertical continuous TOC change curve cannot be obtained, and the test cost is high, which bring great limitations to the evaluation of source rocks. Predecessors have also studied some TOC prediction models, such as the Δlg R method, support vector regression (SVR), and back-propagation neural network, but the TOC predicted by the Δlg R method and SVR has low accuracy and is difficult to calculate. However, back-propagation neural networks always have problems such as local optimal solution and slow convergence speed. In this article, a convolution neural network prediction scheme is proposed. Taking the source rocks of Pinghu Formation in the Xihu Sag as the research object, the advantages of this method are proved by comparing the prediction results of the Δlg R method, SVR, and BP neural network method. The results show that the prediction accuracy of this method is more than 90%, meeting the prediction requirements of TOC. By predicting the TOC curve of Well A, the TOC variation characteristics of Pinghu Formation are finally obtained.
Experiences about calculating ZIP and exponential load model parameters
Authors: Zhang Yiqi , Liao Yuan , Yadav Gaurav
Published: June 2024

To reduce greenhouse emission and achieve sustainability in the electric power industry, improved efficiency and energy conservation are key to finding a sound solution. Energy conservation through voltage reduction (CVR) is one such program. To implement effective CVR programs, load models are of utmost importance in determining proper feeders and methods to implement the CVR programs. Exponential and polynomial load models stand out as the most widely adopted models. The polynomial load model, often referred to as the ZIP (constant impedance, current and power) model, is especially notable for its ability to represent the relationship between the applied voltage and power consumption. This paper sheds light on the limitations of commonly used ZIP load model estimation methods and highlights the significance of using ap-propriate measurement samples and understanding the true nature of the load. Two distinct ZIP load models, i.e., the regular ZIP (RegZIP) and the Non-traditional ZIP (NTZIP) models, have been used for ZIP parameter estimation. The RegZIP load model consumes equal or more power when voltage increases, while the NTZIP model consumes equal or less power when voltage increases. It is emphasized that the RegZIP is an existing load model and the NTZIP is an artificial load model this research created for comparison purposes. The intention of this paper is not to propose any new load model, but to investigate the implications of choosing the wrong model and the impacts of measurement errors of voltage and power data. The research has shown that the two different models can fit the same measurement data equally well for some measured data. The results have demonstrated that simply using certain methods such as the optimization method for estimating load model parameters using unfiltered real time measurements may yield misleading and unreliable results. Wrong load models will inevitably lead to wrong CVR assessment. Identifying the correct measurement samples, obtained during natural or staged events causing substantial voltage variations, is critically important in calculating load parameters and ensure the soundness of the obtained results. The accurate load parameters will be important in the assessment of CVR program effectiveness and will ensure that power system analysis applications that utilize the load models will provide reliable results.

CARE-LEAVERS’ EFFORTS TO BUILD RESILIENCE THROUGH RELATIONSHIPS OF BELONGING
Authors: Reuben Sasambal , van Breda Adrian D
Published: June 2024

This article aims to deepen and theorise our understanding of the need for belonging among young people transitioning out of residential care. The study adopted a qualitative approach, with a sample of 31 residential care-leavers in South Africa, who were followed-up annually for seven years. It addresses the lack of theoretically informed studies and builds an indigenous theory to explain the care-leaving journey. This paper presents findings on care-leavers’ deep desire for authentic belonging, their investment in building authentic relationships, and their frustration and failure in doing so. Implications for practice suggest an imperative to build care-leavers’ sense of belonging after removal from home to care, which will ultimately lead to building resilience. Social workers and child and youth care workers need to co-build networks of belonging to foster young people’s perceptions of themselves and the part that belonging plays in their post-care reintegration. Keywords: aging out of care, belonging, care-leaving theory, leaving care, resilience

Published: June 2024

Istraživanje brodoloma kod otočića Gnalića započelo je krajem šezdesetih godina prošlog stoljeća. Nakon nekoliko pokušaja istraživanje je nastavljeno u sustavnom obliku 2012. godine, pod vodstvom Odjela za arheologiju Sveučilišta u Zadru. Tijekom 2021. godine oslobođen je pristup glavnom brodskom rebru koje se nalazilo u sredini broda. Ove godine nastavilo se s otkrivanjem površine pod kojom se nalaze rebreni nastavci koji pripadaju glavnom rebru, kako bi se utvrdio osnovni oblik broda. Krajem istraživanja, u jednom od kvadrata u središnjem dijelu broda otkrivena je olovna hodočasnička medalja s natpisom na objema stranama. Natpis je u trenutku pronalaska djelovao potpuno nečitko, ali su preliminarno čišćenje i konzervacija omogućili njegovu daljnju analizu, koja je još uvijek u tijeku. Iako je zbog velike količine brodskog balasta istraživanje relativno sporo napredovalo, ove je godine središnji dio broda pripremljen za detaljno čišćenje tijekom sljedeće istraživačke kampanje.

Fiscal Control Management Indicators, Opportunities, and Challenges for Their Implementation
Authors: Hernández Burbano María José , Ortiz Cubillos José Lizardo
Published: June 2024

With the promulgation of Legislative Act 04/2019, whereby the fiscal control system in Colombia is reformed, and the issuance of Decree 403/2020, whereby its implementation is regulated, a great expectation has soared about the construction of a new vision of fiscal control and how its surveillance bodies must fulfill the commitments acquired by Colombia under its accession to the OECD. For this purpose, the main assumptions of the reform and the current constitutional postulates will be identified. This will serve as a normative scenario to explore the options and challenges of the reformed fiscal control regime regarding creating public value based on the implementation management indicators technique. The analysis and conceptual developments of the study intend to make a methodological contribution to the fiscal control bodies and to the National Government itself so that in implementing the reform, it incorporates a holistic view of the measurement of the control of the public sphere.  
It is, in short, an invitation to reflect on the effectiveness of the instruments applied in the public sector, both regarding the measurement of impacts and the achievement of results in the country’s development policies.
Unveiling the effects of nonviolent communication training on youth empathy
Authors: Batūraitė-Bunka Aistė , Jurevičienė Margarita , Skoczowsky-Danielsen Gert
Published: June 2024

Nonviolent communication (NVC) is a model of communication approach, a method, a process, a mindset and a way of life, and was developed by Marshal Rosenberg. NVC offers tools that support the principle of nonviolence and empathic communication. Empathy can be important in promoting pro-environmental behavior (Kansky & Massarani, 2022), and the lack of empathy has been associated with antisocial behavior and reoffending (Bazemore & Stinchcomb, 2004).
The study aims to reveal a self-perceived change in empathy of vulnerable and not vulnerable youth after NVC training.
To conduct the research, a qualitative research methodology was chosen, applying a structured interview survey method. Researchers conducted 10-hour-long NVC trainings for vulnerable and non-vulnerable youth groups and participants were asked open-ended questions in writing. The study demonstrated the feasibility of and relevance to NVC training on (vulnerable) youths‘ empathic communication.

Physical activity through play is a form of expression and development for children and it is defined as any movement produced by skeletal muscles that results in energy expenditure. Physical Exercise is a planned physical activity, structured within a sporting and social context, with an aim to maintain physical conditioning. A competitive athlete is someone who participates in an organized team or individual sport that requires systematic training and regular competitions aimed at a goal, namely a prize or excellence in the sport. There are important physiological particularities in relation to movement and physical conditioning in this stage of the human being’s physical growth and development, with an impact on the cardiovascular system. Currently it is considered that all athletes, regardless of the type of sport practiced, develop a combination of cardiac alterations that simultaneously include dilation and increased thickness of the left ventricular wall. The difference in the intensity of these alterations vary according to factors such as the type of sport practiced, gender, age and body surface area of the athlete. In the adolescent population, especially athletes, it is extremely important to differentiate echocardiographic alterations resulting from intense training with those ones that show some type of cardiac pathology.

Published: June 2024

Background: Sickle cell disease (SCD) is a hereditary chronic haemolytic disorder characterised by repeated vaso-occlusion and chronic haemolysis resulting into chronic complications such as pulmonary arterial hypertension (PAH) and early mortality. Aim: This study is aimed at assessing the arterial blood pressure indices and the clinical implications in individuals with SCA compared with normal Haemoglobin AA among young adult individuals in Nigeria. Subjects and Methods: A total of 132 young adults (18 – 35 years) participated in the study. They were classified into two groups; 69 cases (participants with Hb SS) and 63 age and sex matched controls (participants with Hb AA) which were purposively selected after haemoglobin typing using electrophoresis method. Blood pressure (BP) measurement was done three times after five minute rest using a validated digital sphygmomanometer (Lumiscope) of appropriate cuff size attached to the arm. The average of the last two measurements was calculated and used as the systolic and diastolic blood pressure. Pulse Pressure (PP), Mean Arterial Pressure (MAP), Rate Pressure Product (RPP) was calculated using standard formulae. Data were analyzed using descriptive and inferential statistics and alpha value was set as < 0.05. Results: The mean SBP [110.62 ± 10.55 vs 114.94 ± 9.49 (t=-2.297, p=0.023)], DBP [66.20 ± 7.06 vs 77.06 ± 8.44 (t=-6.956, p<0.0001)] and MAP [81.01 ± 8.21 vs 89.69 ± 7.92 (t=-5.774, p<0.0001)] were significantly lower while the PP [44.42 ± 8.60 vs 37.88 ± 8.14 (t=4.187 ± p<0.0001)] was significantly higher among the participants with SCA. Conclusion: This study showed that SCA is associated with significantly lower SBP, DBP, and MAP with a significantly higher PP when compared with age and sex matched young adults with normal haemoglobin type.

Authors: Dzmitry Valchkevich , Ina Tokina
Published: June 2024

Background: The anatomy of the gluteal arteries is a topic of great importance in clinical practice, as knowledge of their variant structure holds significant value for accurate examination, diagnosis, and treatment of various conditions. Objective: In this article, the main variations in the anatomy of the gluteal arteries are explored. Understanding these variations will enable medical professionals to perform more precise diagnoses and select the most effective treatment methods. Methods: For the current study with the help of anatomical dissection method, 34 cadavers of people aged over 50 years (19 females and 15 males) were investigated. 68 preparations of pelvic arteries in total were studied. In each case the internal iliac artery and its branches, including gluteal arteries were investigated. Results/Conclusion: The individual variability of the gluteal vessels was shown. The inferior gluteal artery has greater variability in comparison with the superior one. Some slight asymmetry is characteristic for gluteal arteries, both in male and female. The anatomical correlation of gluteal arteries with some other vessels of pelvis have been revealed.
Uncommon size of a posterior stafne bone defect: case report
Authors: Campos Paulo Sérgio Flores , Barros Hannah , Prado Gabriela Dias , Filho Bartolomeu dos Santos Sobral
Published: June 2024

Introduction: The Stafne bone defect (SBD) is described as a well-defined, unilateral radiolucent area, usually in the region close to the angle of the mandible and below the mandibular canal. This asymptomatic condition, diagnosed in routine radiographic examinations, affects males between the 5th and 7th decade of life and does not require surgical intervention. The etiology of the condition is uncertain; however, the occurrence of SBD is often associated with salivary gland hypertrophy/hyperplasia. Case presentation: On this report, we present a case of SBD, the posterior variant, exhibiting uncommon dimensions. Conclusion: The Stafne bone defect is most often the result of failure of mandibular ossification.

Published: June 2024

Background: Various methods have been used to estimate age in different populations among them being Willems method which has widely been utilized. In Kenya, there is hardly any approved method that has been used to achieve this purpose, hence the need to determine the available methods for estimating age of children in Western Kenya. Therefore, this study aimed at estimating age using Willems method among children attending dental clinics in Western Kenya. Methods: The study adopted a cross-sectional descriptive design and used Yamane Taro (1967) formulae to find a sample size of 171 orthopantomograms (94males and 77 females) out of 300 panoramic radiographs of children aged between 5-17 years. They were examined by the author in order to determine the tooth maturity stages (A-H) for the first seven mandibular teeth on the left side, accorded maturity scores according to Willems conversion tables for boys and girls and summed up to obtain dental age. Descriptive and inferential statistics were used to analyze data. The results were then presented in tables and figures. Results: The overall mean dental age was 8.94 ± 2.64 with a standard error of 0.173 and that of females and males was 8.75 ±2.28 and 9.10 ±2.24 years respectively at 95% Confidence interval. Conclusion: In conclusion, Willems method revealed an overall underestimation of dental age with no statistical difference between estimated and actual age in both genders among children in Western Kenya.
Modern distributed production (manufacturing) as an important part of the future Ukrainian nationally rooted industry

The purpose of this paper is to propose a variant for the development of a part of the national industry, which would be free from the problems of large investments and threats of unprofitability against the background of innovations. Before the full-scale war, which began in 2022, Ukrainian industry was an offspring and a powerful part of the Soviet heavy industry, mainly of the third technological order. Now, the enterprises that were powerful generators of the national economy GDP are to a greater extent located in the temporarily occupied or front-line territory. Industrial regions suffered significant damage to the production base and infrastructure facilities. The post-war restoration of the domestic industry requires large capital investments, which the national economy is not capable of. In addition, there is a limitation on the duration of investment projects due to the rapid development of modern technologies. According to experts, any project whose implementation exceeds 3 years is risky. In addition, there is a Marxian tendency of the rate of profit to decrease, due to a change in the capital structure, in particular, a decrease in labor expenses. Modern processes of mechanization of production, increase of innovative components (computerization, Internet of things, digitalization, etc.) increase the risks of unprofitability. The authors give an example of the closure of coal mining enterprises in European countries against the background of scientific and technical progress. At the same time, based on the analysis of literary sources, the trend of the spread of the DIY 4.0 phenomenon (from Do It Yourself) was revealed – the use of the most modern technological elements for the manufacture of products designed to meet the manufacturers' own needs. Especially in the USA, the Maker Movement, which is a new culture of industrial activity, is developing. The article substantiates that the technological base of DIY 4.0 and the culture of the Maker Movement are the foundation of the new distributed manufacturing, free from the "curse" of mass investment and unprofitable innovation. It is distributed manufacturing that is able to fundamentally change the quality picture and structure of industry, to ensure the national rooting of industrial production.
