Introduction

Eccentric exercise has often been reported to result in muscle damage, limiting the muscle potential to produce force. However, understanding whether these adverse consequences extend to a broader, functional level is of apparently less concern. In this study, we address this issue by investigating the acute and delayed effects of supramaximal isotonic eccentric exercise on neuromuscular function and motor performance of knee extensors during tasks involving a range of strength profiles, proprioception, and balance.

Methods

Fifteen healthy volunteers (23.2 ± 2.9 years old) performed a unilateral isotonic eccentric exercise of the knee extensors of their dominant lower limb (4 × 10 reps at 120% of one Repetition Maximum (1RM)). The maximum voluntary isometric contraction (MVC), rate of force development (RFD), force steadiness of the knee extensors, as well as knee joint position sense and mediolateral (MLI) and anteroposterior stability (API) of the dominant lower limb, were measured pre-, immediately, and 24 h after the eccentric exercise. The EMG amplitude of the vastus medialis (VM) and biceps femoris (BF) were concomitantly evaluated.

Results

MVC decreased by 17.9% immediately after exercise (P < 0.001) and remained reduced by 13.6% 24 h following exercise (P < 0.001). Maximum RFD decreased by 20.4% immediately after exercise (P < 0.001) and remained reduced by 15.5% at 24 h (P < 0.001). During the MVC, EMG amplitude of the VM increased immediately after exercise while decreasing during the RFD task. Both values returned to baseline 24 h after exercise. Compared to baseline, force steadiness during submaximal isometric tasks reduced immediately after exercise, and it was accompanied by an increase in the EMG amplitude of the VM. MLI and knee joint position sense were impaired immediately after isotonic eccentric exercise (P < 0.05). While MLI returned to baseline values 24 h later, the absolute error in the knee repositioning task did not.

Discussion

Impairments in force production tasks, particularly during fast contractions and in the knee joint position sense, persisted 24 h after maximal isotonic eccentric training, revealing that neuromuscular functional outputs were affected by muscle fatigue and muscle damage. Conversely, force fluctuation and stability during the balance tasks were only affected by muscle fatigue since fully recovered was observed 24 h following isotonic eccentric exercise.

Published: November 2023

The use of unmanned aerial vehicles (UAVs) for pesticide application has increased substantially. However, there is a lack of technical information regarding the optimal operational parameters. The aim of this study was to evaluate the quality of pesticide application on a soybean crop using a UAV employing different spray nozzles. The experiments were conducted using a completely randomized design with four treatments and eight repetitions. The trial was conducted in a soybean growing area during the soybean reproductive stage (1.1 m tall). The treatments included aerial application (rate: 10 L hm−2) using an Agras MG1-P UAV with XR 11001 (flat fan), AirMix 11001 (air-induction flat fan), and COAP 9001 (hollow cone spray) nozzles; for comparison, ground application (rate of 100 L hm−2) using a constant pressure knapsack sprayer with an XR 110015 (flat fan) nozzle was performed. The deposition was evaluated by quantifying a tracer (brilliant blue) using spectrophotometry and analyzing the droplet spectrum using water-sensitive paper. Furthermore, the application quality was investigated using statistical process control methodology. The best deposition performance was exhibited by the application via UAV using the COAP 9001 and AirMix 11001 nozzles. For all the treatments, the process remained under statistical control, indicating commendable adherence to quality standards. The aerial application provided greater penetration of the spray into the crop canopy. With the use of the UAV, the coverage on the water-sensitive paper was <1%; moreover, the AirMix 11001 and XR 110015 nozzles had the lowest drift potential.
Using Information from Public Databases to Critically Evaluate Studies Linking the Antioxidant Enzyme Selenium-Dependent Glutathione Peroxidase 2 (GPX2) to Cancer
Authors: Esworthy R. Steven , Chu Fong-Fong
Published: November 2023

Recent research on selenium-dependent glutathione peroxidase 2 (GPX2) tends to focus on possible roles in tumorigenesis. This is based on the idea that normally generated hydroperoxide species can damage DNA to produce mutations and react with protein sulfhydryl groups to perturb normal regulation of cancer-related pathways. GPX2 is one of many peroxidases available to control hydroperoxide levels. Altered GPX2 expression levels from normal to cancer or with cancer stages seems to be the main feature in bringing it to the attention of investigators. In this commentary, we examine this premise as a basis for cancer studies, largely by trying to place GPX2 within the larger context of antioxidant enzyme gene expression. We make use of public databases and illustrate their possible role in approaching this issue. Since use of such databases is new to us, we looked to sources in the literature to evaluate expression level data, finding general agreement with some discrepancies over the range of expression and relative expression levels among some samples. Using the database information, we critically evaluate methods used to study GPX2 in the current literature for a variety of cancers. Second, groups are now trying to compare enzymatic properties of GPX1 and GPX2 using proteins from bacterial cultures. We weigh in on these recent findings and discuss the impact on the relative GPX2 and GPX1 functions.
A New Hyper-Heuristic Multi-Objective Optimisation Approach Based on MOEA/D Framework
Authors: Han Jiayi , Watanabe Shinya
Published: November 2023

A multi-objective evolutionary algorithm based on decomposition (MOEA/D) serves as a robust framework for addressing multi-objective optimization problems (MOPs). However, it is widely recognized that the applicability of a fixed offspring-generating strategy in MOEA/D can be limited, despite its foundation in the MOEA/D methodology. Consequently, hybrid algorithms have gained popularity in recent years. This study proposes a novel hyper-heuristic approach that integrates the estimation of distribution (ED) and crossover (CX) strategies into the MOEA/D framework based on the view of successful replacement rate (SSR) and attempts to explain the potential reasons for the advantages of hybrid algorithms. The proposed approach dynamically switches from the differential evolution (DE) operator to the covariance matrix adaptation evolution strategy (CMA-ES) operator. Simultaneously, certain subproblems in the neighbourhood denoted as B(i) employ the Improved Differential Evolution (IDE) operator to generate new individuals for balancing the high evaluation costs associated with CMA-ES. Numerical experiments unequivocally demonstrate that the suggested approach offers distinct advantages when applied to a three-objective test suite. These experiments also validate a significant enhancement in the efficiency (SRR) of the DE operator within this context. The perspectives and experimental findings, with a focus on the Success Rate Ratio (SRR), have the potential to provide valuable insights and inspire further research in related domains.

Published: November 2023

This article aims to numerically study the hydrodynamic performance of the bionic dolphin equipped with a pair of rigid pectoral fins. We use dynamic-grid technology and user-defined functions to simulate a novel butterfly-mode flapping propulsion of the fins. This pattern of propulsion is composed of three angular degrees of freedom including the pitch angle ϕp, the azimuth angle ϕa and the roll angle ϕr, which can be divided into four stages for analysis within a single cycle. The stroke of one single pectoral fin can be approximated as an ellipse trajectory, where the amplitudes of ϕa and ϕp, respectively, determine the major and minor axes of the ellipse. The fluid dynamics involved in the specific butterfly pattern is mathematically formulated, and numerical simulation is conducted to investigate the propulsion quantitatively. The results show that the dolphin with a higher water striking frequency f can acquire higher propulsion speed and efficiency. Furthermore, the shape of the ellipse trajectory under different conditions could also have different propulsion effects. The periodic generation and disappearance of vortex structures in the butterfly flapping mode show the evolution process of fluid flow around a pair of pectoral fins, which reveals the influence of motion parameters on fluid dynamics under different working conditions.

Published: November 2023

Pancreatic cancer is a malignant tumor of the digestive system that is highly malignant, difficult to treat, and confers a poor prognosis for patients. BRAF-activated noncoding RNA (BANCR) has been proven to play an important role in the invasion and metastasis of pancreatic cancer. In this study, we focused on BANCR as a potential therapeutic target for human pancreatic cancer. The BANCR level in pancreatic cancer tissues and cells is affected by m6A methylation. Based on this, the aim of our study was to investigate the effect of a highly potent and selective first-in-class catalytic inhibitor of METTL3 (STM2457) on BANCR m6A methylation and its malignant biological behaviors in pancreatic cancer. The relationship between BANCR expression and BANCR m6A modification was detected with RT-qPCR and MeRIP-PCR. The expression of methyltransferase-like 3 (METTL3), the key enzyme involved in m6A methylation, in pancreatic cancer tissues was detected using a Western blot. STM2457 was used in vitro to investigate its resistance to the proliferation, invasion, and metastasis of pancreatic cancer cells. BANCR was overexpressed in pancreatic cancer tissues and cells, which was associated with poor clinical outcomes and validated in pancreatic cancer cell lines. m6A modification was highly enriched within BANCR and enhanced its expression. Remarkably, STM2457 inhibited the proliferation, invasion, and metastasis of pancreatic cancer cells by down-regulating BANCR m6A modifications. This study demonstrates the promise of BANCR as a new diagnostic and therapeutic target for pancreatic cancer and reveals the therapeutic effect that STM2457 exerts on pancreatic cancer by down-regulating BANCR m6A modifications.

Industry 5.0 emphasises social sustainability and highlights the critical need for personnel upskilling and reskilling to achieve the seamless integration of human expertise and advanced technology. This paper presents a methodological framework for designing personalised training programs that support personnel upskilling, with the goal of fostering flexibility and resilience amid rapid changes in the industrial landscape. The proposed framework encompasses seven stages: (1) Integration with Existing Systems, (2) Data Collection, (3) Data Preparation, (4) Skills-Models Extraction, (5) Assessment of Skills and Qualifications, (6) Recommendations for Training Program, (7) Evaluation and Continuous Improvement. By leveraging Large Language Models (LLMs) and human-centric principles, our methodology enables the creation of tailored training programs to help organisations promote a culture of proactive learning. This work thus contributes to the sustainable development of the human workforce, facilitating access to high-quality training and fostering personnel well-being and satisfaction. Through a food-processing use case, this paper demonstrates how this methodology can help organisations identify skill gaps and upskilling opportunities and use these insights to drive personnel upskilling in Industry 5.0.
Pedagogical Design Considerations for Mobile Augmented Reality Serious Games (MARSGs): A Literature Review
Authors: Nelson Cassidy R. , Gabbard Joseph L.
Published: November 2023

As technology advances, conceptualizations of effective strategies for teaching and learning shift. Due in part to their facilitation of unique affordances for learning, mobile devices, augmented reality, and games are all becoming more prominent elements in learning environments. In this work, we examine mobile augmented reality serious games (MARSGs) as the intersection of these technology-based experiences and to what effect their combination can yield even greater learning outcomes. We present a PRISMA review of 23 papers (from 610) spanning the entire literature timeline from 2002–2023. Among these works, there is wide variability in the realized application of game elements and pedagogical theories underpinning the game experience. For an educational tool to be effective, it must be designed to facilitate learning while anchored by pedagogical theory. Given that most MARSG developers are not pedagogical experts, this review further provides design considerations regarding which game elements might proffer the best of three major pedagogical theories for modern learning (cognitive constructivism, social constructivism, and behaviorism) based on existing applications. We will also briefly touch on radical constructivism and the instructional elements embedded within MARSGs. Lastly, this work offers a synthesis of current MARSG findings and extended future directions for MARSG development.

This article presents the results of an assessment of the use of CdSe, NiCdSe, and CoCdSe thin films as a basis for photocatalysts used for the decomposition of the organic dyes rhodamine B, cargo red, and indigo carmine. Interest in this area was determined by the need to solve a number of issues related to increasing the efficiency purifying aqueous media from the negative effects of organic dyes, which cannot be disposed of using traditional methods associated with adsorption or filtration. The use of the electrochemical synthesis method to obtain thin films of a given thickness showed that the addition of nickel or cobalt sulfates to the standard electrolyte solution used to obtain CdSe films results in the formation of CdSe films with a higher degree of structural ordering (the crystallinity degree was more than 50%), as well as a decline in the band gap. When analyzing data on the photocatalytic decomposition of organic dyes, it was found that a change in the structure of the films due to the introduction of nickel and cobalt leads, in the case of the decomposition of the rhodamine B dye, to a more efficient decomposition, and in the case of the cargo red and indigo carmine dyes, not only to their complete decomposition and mineralization, but also to a reduction in the time of photocatalytic reactions (decomposition growth rate). Moreover, an analysis of cyclic tests demonstrated that NiCdSe and CoCdSe films maintain 90% of their photocatalytic decomposition efficiency compared to that achieved during the first decomposition cycle, while CdSe degrades after three consecutive cycles and its efficiency reduces by more than 2.5–3 times.
Investigating the Effect of Organization Structure and Cognitive Profiles on Engineering Team Performance Using Agent-Based Models and Graph Theory
Authors: Estes Judson , Pandey Vijitashwa
Published: November 2023

In large engineering firms, most design projects are undertaken by teams of individuals. From the perspective of senior management, the overall project team must maintain scheduling, investment and return on the investment discipline while solving technical problems. Various tools exist in systems engineering (SE) that can reflect the value provided by the resources invested; however, the involvement of human decision makers complicates most types of analyses. A critical ingredient in this challenge is the interplay of the cognitive attributes of team members and the relationships that exist between them. This aspect has not been fully addressed in the literature, rendering many studies relatively oblivious to team dynamics and organization structures. To this end, we propose a framework to incorporate organization structure using a graph representation. This is then used to inform an agent-based model where team dynamics are simulated to understand the effects of cognitive attributes and team member relationships. In this work, we aim to understand team dynamics in the context of product development. The organization is modeled using the Barabasi–Albert scale-free network. The information regarding member relationships can be acquired through graph metrics such as the various centrality measures associated with the members and the distance between them. This is then used to model the dynamics of the members when they work on a technical problem, in conjunction with their other cognitive attributes. We present some results and discuss avenues for future work.

Authors: Kim Dong-Eun , Lee Tong-Joo , Na Yeop , Noh Ye-Geon
Published: November 2023

Background and Objectives: Since the neck is the weakest part of the metacarpals, the most common metacarpal fracture is a neck fracture, a type which accounts for 38% of all hand fractures. Such fractures can be fixed using a variety of conventional techniques, including intramedullary pinning and K-wire pinning. However, conventional techniques involve complications, such as angulation, stiffness, and rotational deformity. The purpose of this study was to compare the usefulness of our new technique, combined intramedullary pinning with K-wire pinning (IPKP), with those of intramedullary pinning (IP) and K-wire pinning (KP). Materials and Methods: This was a single-center, randomized controlled trial conducted between January 2005 and April 2023. A total of 158 patients with acute displaced fractures of the fifth-metacarpal neck were randomly assigned to either the IPKP group (n = 48), the KP group (n = 60), or the IP group (n = 50). We radiographically evaluated angulation and shortening in three visits: pre-operatively, post-operatively, and at a 1-year follow-up. We clinically evaluated the ranges of motion and Quick-DASH scores to assess daily living performance and the cosmetic scores, using the SBSES score, to assess patients’ satisfaction with their cosmetic outcomes. Results: The IPKP group was superior to the KP group and the IP group regarding radiographical and clinical assessments at the 1-year follow-up visit. The angulation was 15.7° (±7.7) in the KP group, 17.0° (±5.9) in the IP group, and 12.6° (±2.5) in the IPKP group (p < 0.001) at the 1-year follow-up visit. The shortening was 0.9 mm (±0.3) in the KP group, 1.4 mm (±0.2) in the IP group, and 0.4 mm (±0.1) in the IPKP group (m < 0.001) at the 1-year follow-up visit. The TAM was 272.6° (±17.5) in the KP group, 271.1° (±18.0) in the IP group, and 274.1° (±14.9) in the IPKP group (p = 0.42). Four patients (6.6%) in the KP group and two patients (4%) in the IP group were reported as having stiffness, while no patients were found to have stiffness in the IPKP group. The average Quick-DASH score was 2.3 (±0.5) in the KP group, 2.5 (±0.4) in the IP group, and 1.9 (±0.4) in the IPKP group (p > 0.05). The average cosmetic score was 3.7 (±1.2) in the KP group, 3.8 (±0.9) in the IP group, and 4.7 (±0.8) in the IPKP group (p < 0.001). A complication involving nonunion occurred in one case (1.6%) in the KP group, while there were three cases (6%) of rotational deformity in the IP groups. Conclusions: With the IPKP technique, accurate reduction can be achieved to improve hand function and cosmetic outcomes.

Published: November 2023

Several methodologies have been developed to manage diesel in open-cast mining due to its high demand and increasing diesel prices. Although the use of diesel-powered equipment in underground mines has increased over the years, effective management thereof has not received the same attention. With the advent of Industry 4.0, data can be utilised more effectively by modern businesses to identify and solve problems in a structured manner. In this study, an underground mine was used as a case study to determine whether a Data, Information, Knowledge, Wisdom (DIKW) method for diesel management could be coupled with the Six Sigma Define, Measure, Analyse, Improve, Control (DMAIC) tool to make more informed decisions and gain new insights to help reduce diesel wastage underground. The new integrated methodology identified diesel spillages and highlighted the biggest contributors to these underground spillages. The Six Sigma DMAIC domain utilised root cause analysis to determine the reason for recent systems failures, followed by the identification of practical solutions to eliminate up to 200 ML (megalitres) of diesel spillage. With this information, the case study mine stands to save over USD 175,000 per annum.
“Air and Visco” Technique: A Promising Innovation in the Surgical Implantation of the Xen Gel Stent Device
Authors: Franco Fabrizio , Serino Federica , Giansanti Fabrizio
Published: November 2023

We aimed to describe a variation of the surgical technique for the ab interno implantation of the XEN Gel Stent, which, in our experience, is yielding very successful results. The injection of 0.1 mL of air and then of 0.1 mL of a dispersive viscoelastic into the subconjunctival space at the beginning of the surgery allows one to perform a mechanical dissection between the conjunctiva and the Tenon’s capsule, creating a real space. In total, 20 eyes of 16 patients underwent the implantation of a stent gel through the “Air and Visco” technique. We retrospectively analyzed the results. We obtained a reduction in the IOP from an average of 18.3 ± 2.2 mmHg preoperatively to at 13.5 ± 3.5 mmHg at month 12. The needling rate was 20%. We did not register any cases of hypotony (IOP < 6 mmHg), hypotony maculopathy or choroidal detachment. The “Air and Visco” technique allows one to correctly place the device in the subconjunctival space, which the pneumo- and visco-dissection transforms into a real space. This enables an easier surgical performance and more predictable postoperative results, with a low needling rate and reintervention in the follow-up period. It also ensures a greater safety profile because the presence of the OVD on the bleb prevents a sudden lowering of the IOP, eliminating complications such as hypotony, hypotony maculopathy and choroidal detachment in our cohort.

The article considers theoretical approaches to modeling the sustainable development of the Russian banking system in the context of innovative transformations and the formation of digital ecosystems. The relevance of the study lies in the fact that in modern conditions, approaches are increasingly being used to ensure the sustainable development of the banking system based on cognitive modeling, the use of artifi cial intelligence. The scientifi c novelty lies in the fact that in the study, a deep learning model DL-model "Random Forest" was formed, which allows you to get a stable forecast for the net profi t of the banking system, in the conditions of innovative transformations. The practical signifi cance of the study is that the results obtained can be recommended for implementation in practice to provide support for managerial decision-making regarding the sustainable development of the banking system. The cognitive model was developed in the GraphViz environment using a semantic frame network in the form of graphs in the DOT programming language. An analysis of the dynamics of both macroeconomic indicators of the real sector of the economy and the parameters of the development of the banking sector of the Russian Federation was carried out. The criterion for the success of the predictive properties of the DL-model was the value of the average forecast error (MAE). The proposed DL model uses the best decision tree that has optimal hyperparameter settings, for example, the depth of the tree is six layers, the number of estimators (trees) in the ensemble is ten. In the experiment, the hyperparameters of the neural network did not change, the input parameters to various trees were randomly selected by the algorithm.
COMPOSITION AND STRUCTURE OF HYDROPHYTE COMMUNITIES IN DIFFERENT TYPES OF WATER BODIES IN THE CITY OF POLTAVA
Authors: Klepets O.
Published: November 2023

The article highlights the results of studying the composition and structure of the true aquatic plant communities in different types of water bodies of the city of Poltava (artificial and natural reservoirs, the urban section of the middle River Vorskla), where, according to the ecological and floristic classification, 21 associations (including 8 subassociations) of eight alliances, three orders and two classes were identified. Of these, only association Ceratophylletum demersi is the most typical in urban area. The class POTAMETEA differs in the relatively higher coenotic diversity (13 associations), and the class LEMNETEA differs in the lower diversity (8 associations).

The studied plant associations are characterized by a low species richness, the absolute majority of them represents a simplified version of the original natural associations. Communities of class POTAMETEA, observed in urban reservoirs, are especially depleted (1–3 species in the descriptions). There is a general tendency to increase the coenotic activity of the floristic elements that are tolerant to anthropogenic load and eutrophication.

In the rank of associations there are 18 communities in urban lentic water bodies and 9 communities on the urban section of the middle river. Most of the identified associations (12) are confined exclusively to urban reservoirs, while only 3 associations are specific to the urban section of the river. Of those 6 associations found both in urban reservoirs and in the urban section of the middle river, it is the river coenoses that are more diverse and better developed.

In the conditions of an urbanized environment, the middle river ecosystems show a higher resistance to anthropogenic influence compared to ecosystems of artificial urban water bodies, which is evidenced, in particular, by a more complex coenotic structure of common associations, as well as the presence of sozologically valuable communities specifically in the river hydroecotopes.
THE NITROGEN COMPOUNDS CONCENTRATION IN WATER ECOSYSTEMS OF DIFFERENT TYPES
Authors: Basaraba I. , Sukhodolska I.
Published: November 2023

The study researches the changes in the nitrogen compounds concentration (NH4+, NO2¯ і NO3¯) in water ecosystems of different types (the river Stubelka, the Khrinnyky reservoir, Lake Zasvitske and Morozivka quarry) and discusses ecological consequences of their balance shift. The author defines ammonium and nitrites as the predominant form of the nitrogen compounds. It was recorded the exceeding of the maximum permissible concentrations of ammonium nitrogen in the water of river Stubelka (1.16–3.44 times), the Khrinnyky reservoir (1.26-2.06 times), Lake Zasvitske (1.49 times) and Morozivka quarry (1.62 times) that is primarily caused by precipitation, household and agricultural land sewage as a result of mineral and organic fertilizers use. The nitrites concentration exceeds the standard values in the water of the river Stubelka (2.26 times), the Khrinnyky reservoir (1.48-1.77 times) and Lake Zasvitske (3.90-24.64 times) that indicates a slowdown in their oxidation to nitrates and a high risk of secondary pollution of water reservoirs. The nitrates concentration is within the limits of permissible values. It is demonstrated that the nitrogen compounds concentration in water reservoirs changes as follows: NH4+ – river > reservoir > quarry > lake; NO2¯ – lake > river > reservoir > quarry; NO3¯ – reservoir > river > quarry > lake. The balance shift in the ammonium ↔ nitrite ↔ nitrate system towards nitrates is most often characteristic of all water reservoirs in summer and towards ammonium in autumn. NO3¯/NH4+ maximum ratio was found in the Khrinnyky reservoir (94.81), Morozivka quarry (9.55), Lake Zasvitske (5.84) and the river Stubelka (3.80). The pH changes in the water of the river Stubelka (6.7-7.3), the Khrinnyky reservoir (7.0-7.5), Lake Zasvitske (5.9-7.2) and Morozivka quarry (6.5-7.4). The study researches fluctuations in the dissolved oxygen concentration in the water of the river Stubelka (5.7-8.5 mg O2/dm3), the Khrinnyky reservoir (4.4-9.5 mg O2/dm3), Lake Zasvitske (8.6-10.0 mg O2/dm3) and Morozivskyi quarry (8.7-9.3 mg O2/dm3). The concentration of dissolved oxygen in water reservoirs is as follows: lake > quarry > reservoir > river. The presence of an indicator of «fresh» water pollution (ammonium nitrogen) in all reservoirs indicates a constant influx of pollutants, especially intensively to the river Stubelka and the Khrinnyky Reservoir.
PECULIARITIES OF THE STRUCTURE OF THE INTRAHEPATIC BILE DUCTS OF HERBIVOROUS MAMMALS
Authors: Dubinin D.
Published: November 2023

Pathology of the organs of the hepatobiliary system, which happens in the form of calculous and non-calculous cholecystitis, cholangitis of various etiologies and other diseases of the biliary system, occupies one of the first places among surgical interventions on the organs of the abdominal cavity.

Among the adult population, about 10% of those able to work suffer from gallstone disease. This disease is spreading in all countries of the world, and the tendency to its increase is growing. Such an increase in the pathology of the biliary tract is also observed in economically developed countries. Observations show that men suffer less often than women.

The structure of the wall of the intrahepatic ducts is represented by the inner mucous membrane and the outer adventitia membrane. But the structure of their wall in different parts of the liver has its own characteristics. At the beginning of the intraciliary system of the liver, the mucous membrane is represented by epitheliolytic, which have a cubic shape.

The outer shell is represented by cells of the fibroblastic series. In the average department of the internal biliary system of the liver, there is an increase in the size and number of cells in the inner lining of the ducts. Nuclei in the initial division change shape to a bean-like one. Changes in the inner membrane are observed in the terminal part of the intraciliary system of the sheep’s liver. Cells become prismatic and folds can be observed on their apical surface. Nuclei are localized on the basal surface and have a bean-like shape.
MORPHOLOGY OF FEMALE SKULLS OF THE 17th – 18th CENT. FROM BATURYN
Authors: Dolzhenk Yu.
Published: November 2023

This article deals with the publication and the comparative analysis of the 17th – 18th cent. female cranial series from town of Baturyn found during excavations by V. Kovalenko, O. Kovalenko, Yu. Sytyi, V. Mezentsev, V. Skorokhod during 2005–2015 on the territory of the Fortress (the Cathedral of the Life-Giving Trinity) and in resedimentation. Computer software designed by B. Kozintsev and O. Kozintsev in 1991 has been applied in the research. 14 craniometric traits defined by R. Martin have been involved into the analysis.

The objective of this paper is to introduce a new material into scientific domain and define the place of the cranial series among famous anthropological types. To achieve this goal, it is necessary to provide the general morphological description of female group from Baturyn of the 17th – 18th cent. on the background of neighbouring ethnic groups from Ukraine and Eastern Europe (synchronistic and diachronic methods), determine the distance between separate cranial series of the 14th – 19th cent. with the help of multidimensional canonical and cluster analysis, and to find out the place of female population from Baturyn in the system of craniological types of Eastern Europe.

For the first time, the general female series from Baturyn of the 17th – 18th cent. including 33 skulls has been created. After comparison of square divergence of 69 basic traits and indexes of Baturyn female skulls with the standard ones, one can conclude that the researched selection is heterogeneous by its structure. The multidimensional canonical and cluster comparative analyses of the studied female group of the 17th – 18th cent. with the synchronic and earlier series from the 14th – 19th cent. from Eastern Europe (except the Caucasus) have demonstrated its closest similarity to the urban skulls from Podillia.

The comparison of 37 studied groups of the 14th – 19th cent. with the method of multidimensional canonical analysis in three-dimensional space has demonstrated the connection of the female skull sample from the town of Baturyn with two urban groups from Podillia.

Simulations of land use/land cover (LULC) and ecosystem services (ES), which integrate national land policies, reflect the development of land and ecological functions under different scenarios and are crucial for accurately predicting and optimizing urban ecosystem sustainable development. To effectively characterize the urban development trend that complies with urban land policies and spatial differences, we combined major function-oriented zoning (MFOZ) and simulated LULC and ES [including water yield (WY), soil retention (SR), carbon storage (CS), and habitat quality (HQ)] within Beijing–Tianjin–Hebei (BTH) urban agglomeration under multiple scenarios. Based on the improved gray multi-objective optimization (IGMOP) model, the patch-generating land simulation (PLUS) model, and the integrated evaluation of ecosystem services and trade-offs (InVEST) model, three scenarios were designed: business as usual (BAU), economic development (ED), and ecological conservation (EC) scenarios. Results demonstrated higher accuracy with the LULC simulation coupling MFOZ. Under BAU, ED, and EC scenarios, the ecological land (EL) area was 924.99 × 10

, respectively. Compared to 2020, it increased by 0.77% and 1.95% under BAU and EC scenarios and decreased by 0.08% under ED scenario. The LULC changes under different scenarios influenced ES changes. Trade-offs occurred between WY&SR and CS&HQ under BAU and ED scenarios (WY&SR increased, CS&HQ decreased), while different ES types synergistically increased under EC scenario. Impervious surfaces and vegetation positively affected WY&SR, while forestland and impervious surfaces positively and negatively affected CS&HQ, respectively. The simulation coupling MFOZ may provide new insights for exploring more accurate ecological patterns, identifying potential sustainable spaces, and determining priority projects.

Published: November 2023

The purpose of this study was to comprehensively analyze the research trends regarding 'Infant-Teacher Interaction' published in domestic academic journals, in order to provide foundational data for the activation of research on infant-teacher interaction. To achieve this, a total of 93 papers published in domestic academic journals from 2013 to 2022, following the implementation of free infant care, were selected as the subjects of analysis. The study analyzed trends based on the periods of research, target subjects, methods employed, and content. The research findings are as follows First, research related to 'Infant-Teacher Interaction' has been consistently published in various academic journals, with the exception of 2017. Second, the research subjects predominantly focused on infants aged 2 years and younger. Third, in terms of research methods, survey research utilizing questionnaires held a prominent position, surpassing the majority of quantitative studies. Fourth, concerning the content of the research, studies related to teachers, individual factors, and teacher leadership overwhelmingly dominated. Based on these research outcomes, future research directions can be proposed. Research on 'Infant-Teacher Interaction' should not only focus on teacher-related variables but also explore various ecological aspects, including infant and parent-related factors. Additionally, a qualitative research approach is recommended to actively delve into the profound and internal explorations of human variables.
