Authors: Zvarych Roman , Rivilis Igor , Kharkovskyi Bohdan , Masna Olha , Shevchuk Yurii
Published: June 2024

The article defined the concept of waste management in the environmental management system. The research analysed the problems of waste management in the environmental management system from point of view by a number of domestic and foreign scientists. As a result, authors outlined the basic components of waste management: strategic planning, prevention of environmental pollution, conservation of resources, minimization of the amount and toxicity of waste generation, choosing the best prevention option, assessment of effects and consequences, decision-making. The research described the system of green reconstruction of economy and formed the basic principles of the green post-war reconstruction that would provide sustainable economic development. The article outlined the concept of post-war green reconstruction which should focus on such areas as: sustainable construction and resource saving; implementation of renewable energy sources; sustainable development of infrastructure; implementation of a waste management system, minimization of residues. The authors grounded five main stages of waste management process under post-war reconstruction of Ukraine: prevention of waste generation, preparation for reuse, processing, other uses, disposal. Sustainable waste management solutions are essential to maintain environmental harmony but, also, they are linked with cost, public response, political constraints, and social norms. Consumers' environmental awareness influence the demand for goods and services and thus reduce the amount of waste. Research argued that local communities should developed own waste prevention strategies and attract environmentally conscious businesses to their territory. State policy should focus consumers for preferring products in packaging/container that is suitable for recycling or reuse (glass), paper bags, eco-bags, used appliances.

Authors: Yıldırım Nazmiye , Güner Perihan , İnci Figen
Published: June 2024

Objective: The study mainly aims to determine the current state of psychosocial services offered to cancer patients and the views of nurses regarding the ways to meet patients’ psychosocial needs. Other aims to evaluate barriers to meeting patients’ psychosocial needs and measure nurses' difficulty level of psychosocial assessment and intervention practices.

Methods: This multicenter, cross-sectional study was conducted with 1189 nurses providing direct care to adult cancer patients in 32 hospitals in 12 geographical regions of Türkiye. The data were collected by a survey prepared in accordance with the aims of the study.

Results: Three-quarters of the participants reported that their hospital has psychosocial support services while 67.7% stated that this service was provided by psychiatry consultation. Nearly half (49%) stated that all healthcare professionals are responsible for meeting patients’ psychosocial needs, especially it is an integral part of their nursing duties. However, organizational conditions (48.2%-30.7%) are the most important barriers to meeting the psychosocial needs of the patients. Participants have difficulty mostly in assessing and intervening in psychosocial needs of patients mostly in "sexual problems" and "rejection of treatment", and least in "patients’ reactions to illness". Also, the participants have more difficulty in assessing seven of the 19 psychosocial dimensions and intervening in five (P<.05).

Conclusion: This study may be contributed to better structuring of psychosocial services in Türkiye. It can also guide the planning of psychosocial care training. Institutional barriers need to be overcome, especially the nurse-patient ratio, and the psychosocial care capacity of nurses should be improved.

Coordination of the interests of the participants as a tool of successful industry strategizing (on the example of timber industry complex of Russia)
Authors: Shabaeva S. V. , Zhukevich G. V.
Published: June 2024

Strategic approach to the industry development planning is of crucial importance as it helps setting clear goals, determine trends, parameters and conditions for the industry growth. However, low effectiveness of individual industry strategies adopted, their constant adjustments unrelated to strategic orientation, development of “new” strategies duplicating previous documents without meaningful analysis, poor performance discipline on the realization are the evidence of in effectiveness of the methodological approaches used. To cope with the above-mentioned problems, it is essential to pay special attention to the issues of coordination of the interests of the parties which are directly or indirectly involved into industry strategizing. This will ensure finding a balance between the needs and objectives of different participants affecting the success of implementing industry strategies.

The purpose of the study is to consider the peculiar features of industry strategies as the objects of strategizing of the “middle” level, and to identify the mechanisms of harmonization of the interests on the example of the timber industry complex of Russia.

A strategy creates the common value for the parties involved into its development and implementation, including government agencies, industry representatives, sectoral associations, local authorities and public organizations, educational and research institutions. The article deals with the range of issues that are subject to agreement between the participants of “middle” strategies, reflect both the global agenda through state-level strategies, and take into account the interests of local communities. Recommendations suggested as a result of the study can be applied in the development of middle level strategies including sectoral and regional ones.

Published: June 2024

Tendo em vista os recorrentes eventos de movimentos de massa e a complexidade associada à sua causalidade, assim como as severas consequências socioambientais desencadeadas por esses, se faz essencial prever as regiões suscetíveis ao fenômeno. Nesse contexto, o objetivo deste trabalho foi elaborar um método de análise da suscetibilidade a movimentos de massa, a qual foi implementada na região da Área de Proteção Ambiental (APA) Itupararanga, por meio da criação de um sistema de inferência Fuzzy do tipo Mamdani. Foram utilizadas imagens de satélite e outros dados espaciais para a criação dos subsistemas ambiental, pedológico e topográfico, os quais geraram uma saída final utilizada para classificar a susceptibilidade nas categorias muito alta, alta, média, baixa e muito baixa. Os resultados indicam que áreas com maior índice de potencial de fluxo e saturação do solo apresentaram maior susceptibilidade. Além disso, a presença de vegetação e o tipo de solo também foram fatores determinantes. O mapa final de susceptibilidade destacou áreas no norte/noroeste e sul/sudeste como muito suscetíveis a estes eventos, enquanto outras regiões mostraram uma susceptibilidade moderada. Este estudo fornece informações valiosas para o planejamento e gestão adequada de áreas vulneráveis a movimentos de massa.

Embedding-based retrieval: measures of threshold recall and precision to evaluate product search
Authors: Krasnov Fedor
Published: June 2024

Modern product retrieval systems are becoming increasingly complex due to the use of extra product representations, such as user behavior, language semantics and product images. However, adding new information and complicating machine learning models does not necessarily lead to an improvement in online and business search performance, since after retrieval the product list is ranked, which introduces its own bias. Nevertheless, the business performance of a product search will be worse from ranking an incomplete list of products than a complete one, and the relevance of search results will not improve from perfect sorting of products that do not match the search query. Therefore, the main quality indicators for the products retrieval phase remain Recall and Precision at the k threshold. This paper compares several architectures of product retrieval systems in product search for e-commerce. To do this, the concepts of threshold Recall and Precision for information retrieval are investigated and the dependence of these measures on the order of issuance is revealed. An automatic procedure has been developed for calculating R@k and P@k, which allows us to compare the effectiveness of information retrieval systems. The proposed automatic procedure has been tested on the WANDS public dataset for several key architectures. The obtained values R@1000 = 84% ± 9% and P@10 = 67% ± 17% are at the level of SOTA models.
An optimal raw material procurement strategy that minimizes enterprise price risks
Authors: Maron Arkadiy , Maron Maxim , Kazmina Anastasiia
Published: June 2024

This article is devoted to the problem of theoretical and information support for decision-making in strategic management of raw material procurement processes. The study is timely, because there is currently significant volatility in prices for raw materials. This poses very difficult challenges for managers. Finding solutions is one of the most important areas of business informatics. This article discusses a procurement strategy in two stages: at the beginning and middle of the month. The price of raw materials is known only at the beginning of the month. Price is a continuous random variable. You can predict only the interval of its change. Here the interval is directly used to determine the purchase volume at a known price. The authors derived a functional dependence of the maximum risk according to Savage on the amount of purchased raw materials at the beginning of the month. As a result, it was possible to establish the amount of raw materials to be purchased at the beginning of the month to reduce maximum risk to a minimum. Using the example of corn purchases, we carried out a comparative analysis of possible methods for determining these intervals based on an analysis of price time series. The findings are useful for managers of processing enterprises. This work is the first to solve the problem of minimizing the maximum risk when purchasing raw materials.
Application of neural network technologies to assess the competence of personnel in the tasks of controlling the operational risk of a credit institution
Authors: Chumakova Ekaterina , Korneev Dmitry , Gasparian Mikhail , Makhov Ilia
Published: June 2024

The article is devoted to issues of controlling the operational risks of a credit institution associated with the actions of personnel. Operational risk control is an important aspect of a credit institution’s business. Despite the fact that the Bank of Russia in regulatory documents described in detail the set of actions that banks should take to control operational risks, in practice credit institutions experience serious difficulties in dealing with operational risk associated with the actions of personnel. This may be explained, first, by the difficulty of identifying and formalizing the specified risk. One of the main sources of operational risks associated with personnel actions is employees’ lack of qualifications. This can lead to reduced availability and quality of services provided by credit institutions, as well as possible financial and reputational losses. The purpose of the research conducted by the authors is to improve the system of control of operational risks in a credit institution using artificial intelligence technologies, including the development of tools for assessing in an automated mode the level of criticality of the influence of personnel competence on the occurrence of operational risk events. To achieve this goal, an artificial neural network (ANN) was developed using the high-level Keras library in Python. This paper defines a set of key indicators that have the most significant impact on the possibility of operational risk associated with the actions of the personnel in a credit institution. The article presents the results of checking the generated sets of training and test data using application software packages that implement mathematical methods to assess the consistency of the generated data sets. The paper presents graphs showing the results of training and testing of the artificial neural network that has been constructed. The results obtained are new and may allow credit institutions to significantly increase the efficiency of their work by digitalizing the solution of tasks to control the level of operational risk associated with the actions of personnel.

Sensitivity Analysis of Wear on Metal-On-Metal Bearing Couples via Verification of Numeric and Analytic Methods
Authors: Alpkaya Alican Tuncay , Mihcin Senay
Published: June 2024

Wear mechanism is important since it leads to revisions in Total Hip Replacement (THR) surgeries. Contact pressure plays an important role in wear mechanisms and needs to be investigated in detail to obtain more accurate wear predictions to understand the wear performance of the implant in the design stage. This study proposes a methodology for verification of contact pressure and pressure distribution via numeric and analytic methods to be used in wear calculations. Based on Hertz’s contact theory, the contact pressure and the contact area ae calculated in the analytical method. The results are compared to the numeric method’s results obtained from the finite element method. The linear and volumetric wear rates of bearing couples’ surfaces were estimated by Archard’s wear equation. The effect of design parameters on pressure such as head radius, cup thickness, material combination of bearing couples, coating film material, and film thickness are investigated in this study using the proposed methodology. The minimum error between the analytical and numerical results was 0.24% for 28 mm of head diameter, while the maximum error was 11.79 % for 48- mm of head diameter. The minimum contact pressure values were obtained from 48- mm of head radius at a half contact angle of 190 (degrees) in FEM and Hertz calculations, respectively. The maximum linear wear rate was calculated at 0.0026 mm/Mc at a 1- mm cup thickness, while minimum linear wear rate was 0.0022 mm/Mc at a 10- mm cup thickness in the numeric method. The maximum survival cycles of coating materials rate were 31847 cycles for the Stainless-steel coated cup with 500 μm of coating thickness, while the minimum cycles was 2359 cycles for the Ti64 coated cup surface with 100 μm of coating thickness. It is concluded that the most important design parameters are the cup thickness and the material combinations since they have a significant effect on the contact pressure and the contact area. This study provides a verification methodology for the parametric sensitivity analysis before experimental validations. The methodology utilized in this study could be utilized by designers while optimizing the design parameters to minimize the wear.

The “Makarovo” Component of Sosnovyi Bor, Southern Angara, Revisited
Authors: Kuznetsov A. M. , Kogai S. A.
Published: June 2024

The paper presents the findings of a revision of a flint assemblage subjected to aeolian corrasion from Sosnovyi Bor horizon VI, southern Angara, in the Angara-Belaya geoarchaeological region. Initially, the industry was attributed to the “Makarovo Paleolithic Horizon” and dated to the pre-Karga/pre-Murukta stage in accordance with the idea of extreme deflation periods in Siberia. Our revision has resulted in a more accurate assessment of the assemblage composition, correcting the views of the toolkit, flaking strategies, and aeolian corrasion of lithics. We challenge the earlier idea that narrow-faced cores were made on bifaces. Instead, the findings indicate the use of volumetric prismatic and flat-parallel cores with a maximal reduction of residual forms. Two types of blanks are described: blades and bladelets. Small tools include burins, implements with a fashioned tip (“nose” or “spur”), retouched blades (the retouch sometimes extends to proximal parts). Signs of aeolian corrasion range from weak luster to completely worn-off facets and pitted surfaces. Chronological and cultural proximity of Sosnovyi Bor to Makarovo IV industries is questioned despite similarities in post-deposition conditions and flaking, because the tool kits are markedly different. The closest parallels are found among Early Sartan small-blade industries of Trans-Baikal and Yeniseian Siberia. Abrasion could have occurred during the cold and arid maximum of the last glaciation. We conclude that the industry dates to the middle stage of the Upper Paleolithic.

This article presents the results of a study of ceramics associated with the Valdivia and San Pedro complexes at the Real Alto site, southwestern Ecuador. The test sample, studied in 2022, includes fragments of vessels from two morphological and functional groups, relating to the first two phases of the Valdivia culture (bowls and pots) and those representing the San Pedro complex (vessels with necks and a bowl). A comparative analysis was based on identified technological indicators marking various stages of pottery manufacture. Certain differences are seen in the composition of paste and in the hand-shaping of the vessels. Significant differences were revealed in surface treatment and decoration. This is evidenced by the use of colored and plain coating, high-quality solid or matte striped polishing, and complexity of decoration. Distinctive features of firing include the use of different kilns and various atmospheric modes. Parallels include broadly similar firing temperatures. The technological difference between the two morphological and functional groups of the Valdivia complex is that bowls were manufactured with more complex and labor-consuming techniques, whereas pots are technologically somewhat similar to those from San Pedro. Radiocarbon dates (4640–4450 BP) suggest that the two traditions coexisted. Differences may reflect their cultural distinctness.

It consists of 12 small kurgans, each of which contains from one to three differently arranged graves with cremations. The funerary items include typical Fedorovka clay vessels. We estimated the age of bones of domestic animals found on the area under the kurgan or in graves. The new dates were compared with those generated previously. Statistical analysis has made it possible to assess the time range as being from the mid-18th to mid-15th centuries cal BC (medians of calibrated intervals). Dates of the Alakul-Fedorovka complexes fall in the same time range, illustrating the process of interaction between these two traditions. The results of modeling were compared with the dates of the Andronovo sites in Kazakhstan, the Baraba forest-steppe, and Southern Siberia. The dates were similar, barring those of the more ancient series from Kazakhstan. Dates for the Alakul sites in the Trans-Urals were earlier (19th to 16th centuries cal BC), documenting the long coexistence of the Alakul and Fedorovka traditions. In the Southern Trans-Urals, the former tradition appears to have declined earlier. The question as to whether the Fedorovka tradition survived until the Cordoned (Valikovaya) Ware cultures remains open due to the lack of dates for the Cherkaskul culture, which resembles Fedorovka, while being stratigraphically earlier than the Cordoned Ware cultures.
Metal Spearheads from the Bronze Age— New Finds in the Omsk Region
Authors: Borodovsky A. P.
Published: June 2024

This study addresses the morphological features and chronology of the Seima-Turbino spearheads found by chance in the Omsk Region. Their chronology evidences both general and specific features of their distribution. Late specimens attest to a long period of their use in Western Siberia. Special attention is paid to rare spearheads with Janus-like anthropomorphic representations, whose style reveals parallels with both Okunev tradition and Bronze Age anthropomorphic toreutics of China. In the forest-steppe and southern taiga areas of the Middle Irtysh, Seima-Turbino spearheads co-occur with molds for their casting, testifying to local manufacture or replication. Consequently, even undocumented specimens can reveal the meridionally directed (south to north) trade routes. The abundance and diversity of Bronze Age spearheads from the Middle Irtysh provide yet another demonstration of this region’s significance as one of the centers from which Seima-Turbino bronzes spread across southwestern Siberia.

Trace elements in copper artifacts from Late Bronze and Early Iron Age sites in the Urals, formerly attributed to the metallurgical group of “chemically pure” copper, were analyzed using the method of laser ablation inductively coupled plasma mass spectrometry. The metal of which artifacts included in this group are made reveals geochemical markers suggesting that “pure” copper actually falls into several subgroups. The PCA analysis of the results identifies 11 clusters corresponding to various sources of copper ores and their mixtures. At least seven principal associations can be linked to copper deposits of different geological types and origin: Au-Te-Bi, Au-Se-Te-Sb, Fe-Co-Ni-As-Sb, Fe-Co-Ni -Zn, Se-Co-Fe, Ag-Pb-Ni, and Sb-Pb-Zn-As. Also, several mixed associations reflect the fusion of copper items and metal scrap initially obtained from different sources: Sn-Pb, Fe-Co-Ni-Zn + Sn, Fe-Co-Ni + Au-Te-Bi-Ag, Fe-Co-Ni + Au-Te-Bi + Sn. A separate association, for which the ore source remains unknown, consists of artifacts characterized by a low content of trace elements, jointly making up less than 0.01 wt%. The largest sample in the Late Bronze Age “pure copper” group falls within the Sn-Pb cluster representing a mixture of local copper and imported Sn-containing copper scrap. Judging by trace elements, the main sources of ore in the “pure copper” group of the Itkul and Sarmatian cultures were the Gumeshki mine and another unidentified source. Both could have been used already in the Final Bronze Age.
Miniature Anthropomorphic Sculptures from Ust-Voikary: Chronology, Context, Semantics

Published: June 2024

We publish a sample of anthropomorphic sculptures unearthed in 2012–2016 at the Ust-Voikary fortified settlement in the circumpolar zone of Western Siberia. This is one of the permafrost sites, where artifacts made of organic materials are well preserved. The vast majority of the sculptures are made of wood, two of sheet metal, and one from a limonite concretion. Four main categories are identified: busts, heads, relatively full anthropomorphic figurines, and masks on sticks. Most of the sculptures follow the tradition of Ob-Ugric art, while a few can be attributed to Samoyedic art. Some figurines have additional elements such as rows of notches and diamond-shaped signs. According to ethnographic data, these signs endowed the sculptures with a sacral status. The finds have a clear archaeological, architectural, and dendrochronological context. Most were discovered in cultural layers dating to the early 1500s to early and mid-1700s. The artistic style is analyzed, and parallels are cited. The sculptures are compared with 18th to early 20th century ethnographic data. The connection of most figurines with dwellings, their small size and style show that they all belong to the ritual wooden anthropomorphic sculpture and were attributes of domestic sanctuaries. They fall into two main categories: family patron spirits and ittarma—temporary abodes of souls of the dead.
The Tree-Clan-Individual Concept in Traditional Khakas Culture (Late 19th to Mid-20th Century)
Authors: Burnakov V. A.
Published: June 2024

On the basis of ethnographic, folk, and linguistic materials, most of them newly-introduced, the “tree-clan- individual” concept in the Khakas culture is reconstructed and analyzed. The status and image of the tree in their traditional mythological and ritualistic system is assessed. Notions of man and his environment were related to anthropomorphic reasoning, by which natural objects, such as trees, were endowed with human attributes. In their religious-mythological views the tree was identified with a person, with the crown of the tree being the head, the trunk being the body, branches as being arms, sap as being blood, etc. Trees were believed to be either male or female. In the traditional consciousness, human life scenarios were closely paralleled to those of trees. The vegetative code was used to refer to various psychophysical, mental, and other human phenomena. Social norms included special rules in dealing with trees, used in logging. In essence, a tree had to be dealt with like a humanlike being. In mythological thinking, felling a tree was to some degree tantamount to murder. Souls of specific individuals or groups were likewise associated with trees, so each Khakas seok (clan) had a sacred tree. It was an integral part of the burial rite. The tree, then, was a key element in the ideological structure, having a broad semiotic field.
The Origin of the Karasuk People: Craniometric Evidence
Authors: Kozintsev A. G.
Published: June 2024

Measurements of 24 male cranial samples associated with the Karasuk culture were compared with those of 56 other samples using multivariate methods. On the dendrogram, the Karasuk cluster includes the Mongun-Taiga people, Saka, Sauromatians, Tauri, and a group from Sialk B. In the two-dimensional projection, this cluster is intermediate between the Andronovo and Okunev clusters, testifying to the admixed nature of the Karasuk population. In people associated with the Classic Karasuk tradition and in the north of the Karasuk area, the Okunev component predominates, whereas in members of the Kamenny Log tradition and in the south of the area, the proportion of the Okunev and Andronovo components is closer to equal. The use of twelve Andronovo samples conclusively disproves the belief that the sole ancestors of the Karasuk people were Andronovans. Mechanisms whereby Okunev aborigines were assimilated by Andronovo immigrants are discussed.

Polydopamine-mediated facile Silver grown on ZnO Thin Films as High Performance SERS Substrates for R6G Detection
Authors: Pekdemir Sami
Published: June 2024

Surface-enhanced Raman spectroscopy (SERS) is a widely known technique that uses plasmonic structures (silver, gold, etc.) to detect low-concentration molecules. However, the limited number of metallic elements with plasmonic properties leads to limitations in their application. The qualitative detection method of SERS holds considerable promise in providing novel platforms for diverse applications, owing to its utilization of hybrid structures. Mussel-inspired polydopamine offers a promising avenue for the fabrication and integration of hybrid structures suitable for the SERS platform. Here, sputtered ZnO thin films were modified with Ag Nanostructures using polydopamine to fabricate a homogeneous Ag@ZnO hybrid high-performance SERS substrate. Ag/ZnO hybrid nanostructures were analyzed by FESEM and XRD to investigate their morphological and structural characterizations. SERS measurements were performed for all silver growth times to understand the effect of the silver growth process and hybrid structure synergy on SERS performance. The Ag@ZnO hybrid structure, cultivated with 24-hour silver growth, exhibited remarkable detectability even at an ultra-low R6G concentration of 10 pM

Published: June 2024

SrS:Eu is known as an attractive material for imaging, scintillator, or persistent phosphor applications, thanks to its effective photoluminescence (PL) and thermoluminescence (TL) capabilities, but there are still great mysteries of persistent phosphors and attract great interest. Hence, this work investigated the luminescence properties of well-known persistent phosphor based on SrS using various spectroscopic techniques for detailed characterization. Measurements using X-ray photoelectron spectroscopy (XPS) and X-ray diffraction (XRD) were used to analyze the phase and elements of the phosphor. Belongs to the XRD data the microcrystalline phosphor is cubic, and the diameters ranged from 1 to 100 µm. The morphology of the phosphor was examined by scanning electron microscope (SEM). A time-resolved PL system recorded PL properties, namely the emission and excitation spectra of the phosphor. SrS emits around 626 nm with a broad excitation band peaking around 466 nm. A TLD reader system measured the TL glow curve of the phosphors after UVB radiation. The TL glow curve exhibited a broad peak around 160oC. The dose-response of this peak was obtained up to 600 seconds of exposure to UVB radiation, and it was observed that the dose-response curve exhibits a saturating exponential behavior.
