In the context of permanent changes caused by instability due to the ongoing war and an increased uncertainty in the business environment, the conditions for the development of enterprises are changing dramatically. The article elaborates an interpretation of enterprise development as a process of quantitative, qualitative, and structural changes in its status (potential) and functional activity to achieve the established vision and goal (effectiveness), which are caused by an immanent tendency to improvement. The concept of development of a socioeconomic system is considered. The interaction of the main elements of the development of the socioeconomic system is analyzed. Both the conceptual and the basic models of enterprise development management have been elaborated. Studies have shown that in the current economic conditions, business activity is a decisive factor in the economic performance of an enterprise. At the same time, business activity is a defining characteristic of the company’s position in the market. Thus, the growth of business activity of an economic entity in the capital, goods, and labor markets, aimed at improving the effectiveness of its activities, becomes the primary task of the economic development of the enterprise. It is determined that the results of activity characterize the degree of achievement of the goal of development of enterprise, which is described by an aggregate of indicators. Changes that may occur during the implementation of a certain conception of development primarily affect such functional characteristics as capital, sufficient costs of production, output. Estimates of such changes can be obtained based on the results of experimentation with the corresponding searching (working) models. On the basis of the above and taking into account the best practices of project management, strategies and models of enterprise development are considered, including strategies for growth, activation, transformation and creation. These strategies provide elemental, mixed, and system types of development.

Published: November 2023

The aim of the article is a theoretical and methodological substantiation of the scientific and practical process of the strategic development of startups in the innovative environment in the current conditions of economic management. According to the results of the carried out study, it is found that the successful development of the economy of any contemporary country is directly related to the level of innovative development and access to the markets of advanced technologies. The process of generation and implementation of innovations is the basis for successful transformation into a modern knowledge-intensive and dynamically developing market economy. One of the key factors ensuring the effectiveness of this process is the creation of an innovation infrastructure, an important element of which is startups as the most operational and flexible market of participants. It is generally accepted that the evaluation of a startup is a sign of success. This indicates progressive development and attractiveness for involving financial sources. However, unlike the valuation of the State-owned companies, the process for private companies is opaque and often based on assumptions made after the announcement of late investment rounds. This approach does not allow for an objective evaluation of a startup. The shares issued at later stages are more expensive – not only because of the objective success of the company, but also because of specific preferences. The article discusses the advantages of creating startups, identifies trends in increasing innovative development and proposes long-term development of a startup at all life cycles. It is determined that the reorganization of the innovation infrastructure for supporting startups includes solving the current and strategic tasks related, first of all, to investment support for the generation of innovation. Taking into account the complexity of the structural composition of the elements involved in the processes of creation and development of innovative infrastructure to support startups, and the strategic orientedness of the tasks they solve, the development of the organizational structure and economic mechanism of interaction between startups is the basis for the development of innovation infrastructure, contributing to the effective organization of information exchange between the elements of the innovation infrastructure.

The global trend of transition to a green economy has become a key component of the development of developed countries. This process is driven by many factors, including growing awareness of climate change, pollution, and the need to ensure the sustainable use of natural resources. Developed countries are actively implementing green technologies, promoting the use of renewable energy sources, and supporting the creation of sustainable infrastructure that helps reduce greenhouse gas emissions. This trend is also reflected in policy decisions and legislation aimed at encouraging environmentally friendly production and consumption. The green economy is becoming a source of innovation and new opportunities for job creation and increasing the competitiveness of countries in the global market. However, this process also requires serious efforts and investments in the research and development of new technologies, as well as in the training of the workforce for green economy sectors. The global trend of transition to a green economy is an important step in preserving the environment and ensuring sustainable development in the future. The need to transform Ukraine’s economy within the framework of the green economy is a relevant and urgent task. The country is facing complex challenges related to climate change, the depletion of natural resources, and environmental pollution. The green economy is an important instrument for ensuring sustainable development and reducing the negative impact on the environment. The transformation of the economy includes the transition to the use of renewable energy sources, support for energy efficiency, the development of environmentally friendly technologies and green infrastructure projects. This transformation can provide new markets and jobs, foster innovation, and increase Ukraine’s competitiveness in the global market. In addition, the green economy helps to reduce dependence on energy imports and ensures the country’s energy security. The role of the government in creating a favorable legal environment and incentive mechanisms for the development of green technologies and investment in green projects is also important. The coordinated transformation of the economy in a green direction meets global challenges and is a strategic step to ensure sustainable development and improve the quality of life of Ukrainian citizens.

Authors: Jahan MA , Ahmed F
Published: November 2023

A pot experiment was conducted in the vinyl house of Sher-e-Bangla Agricultural University (SAU), Dhaka-1207, during kharif-I season (March to June 2022) to identify waterlog tolerant mungbean genotypes. Thirty mungbean genotypes (29 advanced lines and one variety, BARI Mung-6) were evaluated under waterlogging (96 hours) and normal conditions. Waterlogging caused a drastic reduction in dry matter and seed yield in mungbean, however, genotypes showed variable response to waterlogging. Under waterlog condition the higher relative yield was found in M11, M8, M30, M7, M16 and M14 while lower in M2 and M17. Dry matter production also varied among the genotypes due to waterlogging; however, dry matter production of the genotypes M8, M7, M22, M2, M19 and M11 were comparatively higher than other genotypes. Stress tolerance index (STI), yield index (YI) and relative yield (RY) of M16, M20, M7, M8, M11, M30 and M14 were higher than other genotypes. On the basis of dry matter production, STI, YI and RY, genotypes M7, M8, M11, M12, M16, and M20 could be selected as relatively tolerant genotypes against waterlogging stress.

Published: November 2023

Purpose: We prospectively evaluated the surgical outcomes of non ligation of hernial sac technique in children with a palpable undescended testis compared with the traditional hernial sac ligation technique during orchiopexy.

Material and Methods: A total of 34 orchiopexies (30 children with age ranged from 6 months to 5 years) were included and randomly assigned to the non ligation of hernial sac technique orchiopexy group (Group-A, 15 children, 16 testes) and the traditional hernial sac ligation orchiopexy group (Group-B, 15 children, 18 testes). Operation time and surgical complications were compared between the two groups. Complications, testicular location and development of inguinal hernia were assessed at the follow-up evaluation for 6 months postoperatively.

 Results: The operation time was significantly shorter in Group-A (34.13±10.3 minutes) than Group-B (73.73±28.97 minutes) (<p001). Postoperative complications were found in two cases (wound infection and testicular re-ascent) in Group-B. Wound infection was managed by conservative care and redo surgery was done for testicular re-ascent after 6 months of operation. None of the patients developed post operative inguinal hernia.

 Conclusion: We conclude that non ligation of hernial sac technique is a simple procedure that is associated with a shorter operation time than the conventional hernial sac ligation technique during open orchiopexy for palpable undescended testis.

An increase in the survival rate of patients who had cancer in childhood determines the need to study the long-term consequences of the treatment. Long-term complications may develop from various organs and systems: active studies of the toxicity of chemotherapy are carried out in the ﬁeld of pharmacogenetics, respiratory, cardiovascular, sensorineural and endocrine systems, as well as skin, central nervous system, immune system and others. The treatment of acute leukemia carried out in childhood can signiﬁcantly reduce the quality of life, cause cognitive and psychoemotional disorders. Experts in the ﬁeld of pediatric hematology-oncology proposed to create an indicator called «survival without pronounced toxicity». A group of scientists initiated an international project to study the outcomes of childhood malignant tumors. Among the long-term consequences, it is planned to assess the quality of life and the development of complications. The study of long-term complications of leukemia treatment will allow us to develop algorithms for the prevention and follow-up of these patients.

A System to Support Readers in Automatically Acquiring Complete Summarized Information on an Event from Different Sources
Authors: Dell’Oglio Pietro , Bondielli Alessandro , Marcelloni Francesco
Published: November 2023

Today, most newspapers utilize social media to disseminate news. On the one hand, this results in an overload of related articles for social media users. On the other hand, since social media tends to form echo chambers around their users, different opinions and information may be hidden. Enabling users to access different information (possibly outside of their echo chambers, without the burden of reading entire articles, often containing redundant information) may be a step forward in allowing them to form their own opinions. To address this challenge, we propose a system that integrates Transformer neural models and text summarization models along with decision rules. Given a reference article already read by the user, our system first collects articles related to the same topic from a configurable number of different sources. Then, it identifies and summarizes the information that differs from the reference article and outputs the summary to the user. The core of the system is the sentence classification algorithm, which classifies sentences in the collected articles into three classes based on similarity with the reference article: sentences classified as dissimilar are summarized by using a pre-trained abstractive summarization model. We evaluated the proposed system in two steps. First, we assessed its effectiveness in identifying content differences between the reference article and the related articles by using human judgments obtained through crowdsourcing as ground truth. We obtained an average F1 score of 0.772 against average F1 scores of 0.797 and 0.676 achieved by two state-of-the-art approaches based, respectively, on model tuning and prompt tuning, which require an appropriate tuning phase and, therefore, greater computational effort. Second, we asked a sample of people to evaluate how well the summary generated by the system represents the information that is not present in the article read by the user. The results are extremely encouraging. Finally, we present a use case.
Developing Dimensions and Indicators to Measure Decentralization in Decentralized Autonomous Organizations
Authors: Park Hyejin , Ureta Ivan , Kim Boyoung
Published: November 2023

Decentralization holds a significant role in the context of decentralized autonomous organizations (DAOs), with its nature being not a fixed value but a comparative spectrum. Prior research investigating the measurement of decentralization in nations’ governance system provides a foundation for our current study. This research aims to integrate these insights to define dimensions and indicators, tailored explicitly for assessing decentralization levels within DAOs. Then, the article undertakes an examination of the suitability of traditional decentralization measurement approaches within the unique DAO context, employing confirmatory factor analysis (CFA) as our analytical tool based on a total of 44 DAOs. Hence, the results suggest that DAOs have three dimensions for measuring decentralization, ‘political decentralization as a participatory engagement’, ‘economic decentralization as a resource distribution’, and ‘administrative decentralization as the self-governing execution of decisions’. By substantiating the applicability of established decentralization measurement frameworks within the unique context of DAOs, the findings not only enhance the understanding of this emergent governance paradigm but also provide DAO practitioners, policymakers, and researchers with invaluable insights.

Published: November 2023

Although the Port of Corpus Christi, Texas, has become a top oil exporter, it is unknown if local dolphins are disturbed by high year-round vessel traffic. A shore-based digital theodolite and automatic identification system receiver were used to record data to assess common bottlenose dolphin (Tursiops truncatus) behavioral states and movement patterns in the Corpus Christi Ship Channel (CCSC) in relation to vessel traffic. Multinomial logistic regression and generalized additive models were applied to analyze the data. Vessels were present within 300 m of dolphins during 80% of dolphin observations. Dolphins frequently foraged (40%), traveled (24%), socialized (15%), and milled (14%), but rarely oriented against the current (7%) or rested (1% of observations). Season, time of day, group size, vessel type, vessel size, and number of vessels were significant predictors of dolphin behavioral state. Significant predictors of dolphin movement patterns included season, time of day, group size, calf presence, vessel type, and vessel numbers. The CCSC is an important foraging area for dolphins, yet the high level of industrial activity puts the dolphins at risk of human-related disturbance and injury. There is a crucial need to monitor the impact of increased anthropogenic influences on federally protected dolphins in the active CCSC, with broad application to dolphins in other ports.

Published: November 2023

The rules of team sport have been influenced by professional competitions without considering all the factors that differentiate children and adolescents from adults. The aim of this study was to analyse the performance of kinematic variables in two different types of tournaments and the influence of somatic maturation on performance in young basketball players. Thirty-seven under-13 male basketball players (age = 12.91 ± 0.57 years) were selected by four southeast Spanish teams to participate in two different tournaments. On the first day, the tournament was played according to the rules of the Spanish Basketball Federation (FEB) for under-14 players, and on the second day, the tournament was played according to modified rules (Modified Tournament). In this tournament, the height of the basket was lowered to 2.90 m; the three-point line was a rectangle that was 4 m from the basket.The following kinematic variables were analysed: Acceleration (n), Deceleration (n), Maximum Acceleration Speed (km/h), Maximum Deceleration Speed (km/h), Acceleration Meters Covered (m), Deceleration Meters Covered (m), Number of Sprints (n), Sprint Meters Covered (m), Maximum Sprint Speed, and Player Load (n). The results showed no significant differences in player performance between the tournaments. However, significant differences in performance (p < 0.05) were found in players at different stages of maturation. Early maturity players showed the best performance in the kinematic variables in both tournaments; because of this, there should be a modification of the rules and organisation of competitions by bio-banding. It can be concluded that there were no significant differences in the kinematic variables between the two tournaments. However, when comparing maturation timing, there tends to be a group effect.

Published: November 2023

With the current upsurge in the desire to foster healthy lifestyles and consume nutritious food products, the food industry has been propelled to develop novel food processing technologies. In our study, we critically evaluated the influence of pulsed electric field (PEF) processing by comparing it to conventional thermal pasteurization protocols—low temperature, long time (LTLT), high temperature, short time (HTST), and microfiltration (MF)—and its ramifications on the nutritional properties inherent in raw milk, which comprises vitamins, whey protein, amino acids, cholesterol, and fatty acids. A significant difference in β-lactoglobulin content was observed in PEF-treated liquid whey samples compared to those treated with high-temperature (HT) pasteurization, where 4.8-fold reduction with a concentration of 0.80 mg/mL was observed. Liquid whey samples treated with PEF, LTLT, HTST and MF retained β-lactoglobulin content, PEF-treated samples yielded 3.85 mg/mL, while HTST, LTLT, and MF-treated samples had β-lactoglobulin content of 3.62 mg/mL, 3.63 mg/mL, and 3.62 mg/mL compared to raw whey control (RWC) at 3.81 mg/mL. The concentrations of nutritional properties, like vitamins (A, D, E), amino acids, cholesterol, and fatty acids, remained approximately consistent across all the pasteurization methodologies. Moreover, the bacterial viability in the context of various pasteurization methodologies was scrutinized, with an absence of colonies observed in whey specimens subjected to thermal pasteurization. PEF-treated samples exhibited a substantial 1.6-log reduction in coliform colony count to less than 4 CFU/mL after curd reduction, in contrast to raw milk samples.

The excessive noise present within an aircraft cabin during flight operations constitutes a notable origin of fatigue, stress, and communication impediments for both pilots and passengers. Ensuring the comfort, well-being, and safety of passengers and crew members necessitates the accurate anticipation of noise levels. This study concerns the computation of structure-borne noise levels within the cabin of a tiltrotor aircraft. This investigation employed two distinct methodologies: advanced transfer path analysis (ATPA) and statistical energy analysis (SEA). To assess the results obtained with the ATPA approach, the acquired outcomes were compared with empirically measured sound pressure levels during airplane mode operations. The contributions of air-borne and structure-borne noises were calculated with the ATPA methodology. On the other hand, the structure-borne noise was calculated with a hybrid experimental–SEA model with ACTRAN software, and its results were compared with those of the ATPA method. The results show a good agreement between these methods at high frequencies, while at low frequencies, certain adjustments or modifications to the SEA model are necessary to predict the noise levels.

Phasor Measurement Units (PMUs) are the backbone of smart grids that are able to measure power system observability in real-time. The deployment of synchronized sensors in power networks opens up the advantage of real-time monitoring of the network state. An optimal number of PMUs must be installed to ensure system observability. For that reason, an objective function is minimized, reflecting the cost of PMU installation around the power grid. As a result, a minimization model is declared where the objective function is defined over an adequate number of constraints on a binary decision variable domain. To achieve maximum network observability, there is a need to find the best number of PMUs and put them in appropriate locations around the power grid. Hence, maximization models are declared in a decision-making way to obtain optimality satisfying a guaranteed stopping and optimality criteria. The best performance metrics are achieved using binary integer, semi-definite, and binary polynomial models to encounter the optimal number of PMUs with suitable PMU positioning sites. All optimization models are implemented with powerful optimization solvers in MATLAB to obtain the global solution point.

Inadequate response to balance perturbations lead to posture instability in the elderly. The fall risks are increased by a reduced capacity to control the center of pressure (COP) displacement within the safety limit of the supporting base. This study developed an interactive evaluation and training platform. The system incorporated a computerized program with instantaneous force plate evaluation. Ten young subjects underwent a baseline evaluation and twenty-nine community-dwelling elderly received pre- and post-intervention testing. The ability to reach the stability limit was assessed by measuring the maximum voluntary excursion of the COP in anterior–posterior and medial–lateral directions. Functional mobility tests including Berg Balance Scale, Timed-Up-and-Go and functional reach were used as functional outcomes. The experimental group (n = 15) received a 40 min intervention three times a week for six weeks. The interactive game-based training focused on multi-directional weight shifting by tracing a COPcontrolled target to challenge an individual’s stability limit. The control group (n = 14) maintained daily activities as usual. The young group revealed a superior COP displacement through active ankle control than the elderly, especially in the anterior–posterior direction. The experimental group improved their COP displacement control more in the medial–lateral direction due to the predominant side-to-side gameplay movement. The functional outcome measures were also significantly improved after training. Using the COPcontrolled game-based program, the stability limit was challenged to facilitate dynamic posture control by an incremental increase in self-initiated perturbations. The platform system could assist in transferring the immediate training effects into daily functional mobility in the elderly.

Biomaterials are currently a unique class of materials that are essential to improving the standard of human life and extending it. In the assent of the appearance of biomaterials that contain non-toxic elements, in this study, we examine a system of Ti25Mo7Zr15TaxSi (x = 0, 0.5, 0.75, 1 wt.%) for future medical applications. The alloys were developed in a vacuum electric arc furnace and then studied from a structural, mechanical and in vivo assessment (on rabbits) perspective. The effect of the silicon addition was clearly seen in both the structural and the mechanical characteristics, standing out as beta alloys with a dendritic structure and lowering the mechanical properties as a result of the silicon addition. In experimental rabbits, the proliferation of mesenchymal stem cells was observed in the periosteum and peri-implant area, differentiating into osteoblasts and then into osteocytes. Osteoclasts were discovered within the cartilaginous islands that provide structural support to newly formed bone, playing a primary role in bone remodeling. The newly formed spongy tissue adhered to the fibrous capsule that surrounds the alloy, ensuring good osseointegration of metallic implants. The overexpression of Osteopontin, Metalloproteinase-2 (also known as gelatinase A), and Metallopeptidase-9 (also known as gelatinase B) underscores the processes of osteogenesis, bone mineralization, and normal bone remodeling.
