Energy efficiency features of vernacular house in Bosnia and Herzegovina: A case study of Svrzo’s house complex
Authors: Martinovic Sandra , Zecevic Nurin
Published: May 2023

This paper analyzed sustainable principles of vernacular architecture in Bosnia and Herzegovina featured in the Svrzo’s house complex in Sarajevo, which can serve as an example that can be utilized in contemporary architecture. An energy-efficiency analysis was performed by using DesignBuilder software. The aim was to investigate whether the building design, building’s envelope materialization, and spatial organization comply with today’s energy-efficiency standards and if such principles can be applied in contemporary design. The calculation of the energy demands for heating and cooling showed that the division of the house in winter and summer quarters is an energy-efficient approach that could be transposed into contemporary architecture. The calculations also showed that the materialization of the building envelope of the winter quarter is not energy efficient enough to be used in modern constructions, but the positive aspects of the building envelope materialization such as the use of natural, local materials with good heat capacity are important elements which could serve as guidelines for the materialization of contemporary buildings. Therefore, a new materialization was proposed on the basis of these principles. The calculations showed that the analyzed winter quarter became energy-efficient while maintaining sustainable principles borrowed from vernacular architecture.

The author continues a series of works in which, based on a country-by-country analysis of rating data for 2021, he analyzes the present state of the socio-economic development in the Russian economy, as well as its prospects and vulnerabilities. Among the key reasons hindering the innovative development of the Russian economy are the lack of decent conditions for the creation and development of innovative companies, the systematic loss of opportunities to increase momentum in the field of high-tech knowledge-intensive technologies, an inefficient public administration system, the outflow of highly qualified specialists abroad, lack of funding for science and education, depreciation of fixed assets, underdevelopment of the logistics and transport infrastructure systems, accumulated social problems, etc. The author draws the attention to the fact that in order to achieve an accelerated innovative development of the Russian economy, is necessary to make a transition to medium-term and long-term strategic planning.
An alternative to hybrid state controlled capitalism
Authors:   10.37930/1990-9780-2023-2-76-75-78, Lane D.
Published: May 2023

The paper critically analyzes various interpretations of the concept of state capitalism. The author differentiates the state as the owner of the means of production, state as a form of economic coordination, state as the dominant institution of political power, and state as an instrument for extracting and distributing surplus value. The failure of post-socialist European countries to transition to a sustainable market capitalist system, as well as the rise of state-managed hybrid market economies in China, have led to such economies becoming long-term economic formations. A hybrid economy, in which a market-capitalist sector coexists with a politically controlled and dominant public sector, is proposed as an alternative to neoliberal forms of coordination. It provides the foundation for the development of a rational political economy.

The purpose of this study was to describe the implementation of learning arts and culture (music) in class VIII.2 at SMP Negeri 3 Sungai Geringging. Researchers used qualitative research that is descriptive. The main instrument in this study was the researcher himself observing the learning process for class VIII.2 on the subject matter of music at SMP Negeri 3 Sungai Geringging. The type of data used is primary and secondary data. Data collection techniques were carried out by means of literature study, observation, interviews, and documentation. The steps to analyze the data are data collection, data reduction, data presentation, and drawing conclusions. The results of the study concluded that the process of implementing art and culture learning for music material in class VIII.2 had not gone well. This is because there are obstacles in which there are no learning media, and there is no infrastructure for musical instruments, as well as practice rooms so the teacher does not teach in accordance with the existing syllabus and lesson plan (RPP). Learning the art of music in class VIII.2 is one of them only fulfilling the core competency indicators in the syllabus, namely "understanding" traditional musical instrument material. Then the problems that occur in the class are the visible attitudes of students when participating in learning the art of music, students look bored and bored participating in learning traditional musical instruments, then there are some students who are seen often having permission to go in and out of class, chatting with their peers, ignoring the material provided teachers, so that they do not respond well to learning. Based on the results that have been concluded by researchers, students feel bored, experience boredom, and do not respond well to the material taught by the teacher, because learning the art of music is mostly done in theory only, while practice is never carried out and taught to students because there is no infrastructure. -musical instruments available, and a room for practicing musical art. In the teaching and learning process, there is no learning media available, then the methods taught by the teacher do not vary, the teacher more often uses the lecture and question and answer method only. So that in reality the learning objectives that must be achieved in the teaching materials owned by the teacher have not been achieved optimally.
Can Protostellar Outflows Set Stellar Masses?
Authors: Myers Philip C. , Dunham Michael M. , Stephens Ian W.
Published: May 2023

The opening angles of some protostellar outflows appear too narrow to match the expected core–star mass efficiency (SFE) = 0.3–0.5, if the outflow cavity volume traces outflow mass, with a conical shape and a maximum opening angle near 90°. However, outflow cavities with a paraboloidal shape and wider angles are more consistent with observed estimates of the SFE. This paper presents a model of infall and outflow evolution based on these properties. The initial state is a truncated singular isothermal sphere which has mass ≈ 1 M
⊙, freefall time ≈ 80 kyr, and small fractions of magnetic, rotational, and turbulent energy. The core collapses pressure free as its protostar and disk launch a paraboloidal wide-angle wind. The cavity walls expand radially and entrain envelope gas into the outflow. The model matches the SFE values when the outflow mass increases faster than the protostar mass by a factor 1–2, yielding protostar masses typical of the IMF. It matches the observed outflow angles if the outflow mass increases at nearly the same rate as the cavity volume. The predicted outflow angles are then typically ∼50° as they increase rapidly through the stage 0 duration of ∼40 kyr. They increase more slowly up to ∼110° during their stage I duration of ∼70 kyr. With these outflow rates and shapes, the model predictions appear consistent with observational estimates of the typical stellar masses, SFEs, stage durations, and outflow angles, with no need for external mechanisms of core dispersal.
Statistical Recovery of 21 cm Visibilities and Their Power Spectra with Gaussian-constrained Realizations and Gibbs Sampling
Authors: Kennedy Fraser , Bull Philip , Wilensky Michael J. , Burba Jacob , Choudhuri Samir
Published: May 2023

Radio interferometers designed to probe the 21 cm signal from Cosmic Dawn and the Epoch of Reionization must contend with systematic effects that make it difficult to achieve sufficient dynamic range to separate the 21 cm signal from foreground emission and other effects. For instance, the instrument’s chromatic response modulates the otherwise spectrally smooth foregrounds, making them difficult to model, while a significant fraction of the data must be excised due to the presence of radio-frequency interference, leaving gaps in the data. Errors in modeling the (modulated and gappy) foregrounds can easily generate spurious contamination of what should otherwise be 21 cm signal-dominated modes. Various approaches have been developed to mitigate these issues by, for example, using nonparametric reconstruction of the foregrounds, in-painting the gaps, and weighting the data to reduce the level of contamination. We present a Bayesian statistical method that combines these approaches, using the coupled techniques of Gaussian-constrained realizations and Gibbs sampling. This provides a way of drawing samples from the joint posterior distribution of the 21 cm signal modes and their power spectrum in the presence of gappy data and an uncertain foreground model in a computationally scalable manner. The data are weighted by an inverse covariance matrix that is estimated as part of the inference, along with a foreground model that can then be marginalized over. We demonstrate the application of this technique on a simulated Hydrogen Epoch of Reionization Array–like delay spectrum analysis, comparing three different approaches for accounting for the foreground components.

Estimation of selectivity parameters for target and bycatch fishes of the trammel net fisheries in the northern Aegean Sea (eastern Mediterranean Sea)
Authors: Adamidou Angeliki , Touloumis Konstantinos , Koutrakis Manos , Tsikliras Athanassios C.
Published: May 2023

The size selectivity of trammel nets was investigated in the northern Aegean Sea using 10 different inner-panel mesh sizes ranging from 16 to 70 mm nominal mesh size (bar length). Selectivity estimates were made for the eight most abundant target and bycatch fish species, namely black scorpionfish, Scorpaena porcus Linnaeus, 1758; annular seabream, Diplodus annularis (Linnaeus, 1758); red mullet, Mullus barbatus Linnaeus, 1758; surmullet, Mullus surmuletus Linnaeus, 1758; round sardinella, Sardinella aurita Valenciennes, 1847; European hake, Merluccius merluccius (Linnaeus, 1758); greater weever, Trachinus draco Linnaeus, 1758; and blotched picarel, Spicara flexuosum Rafinesque, 1810, which accounted for 51.5% by number and 42.7% by weight of the fish caught with trammel nets in the sea trials. The SELECT method was used to estimate the selectivity parameters. Five different selectivity functions (i.e., normal scale, normal location, gamma, log-normal, and bi-normal) were applied with the bi-normal function providing the best fit as it had the lowest deviance value for all species and the lowest values for the dispersion parameter (D/df). The mesh size of 16 mm in most of the cases retained specimens below the size at first maturity (Lm). The mesh size of 19 mm seems more appropriate for red mullet, surmullet, and blotched picarel, the mesh size of 22 mm for annular seabream and round sardinella, while for European hake and black scorpionfish, the mesh size larger than 26 mm would be more appropriate.
Study the activity of conjugated antimicrobial peptide WW-185 against clinically important bacteria
Authors: Salama Ali H.
Published: May 2023

Multidrug-resistance bacteria are a serious problem for health specialists and all the people in the world. The main reasons for this problem are the misuse of antibiotics and the limited number of antibiotics as compared to the different human diseases. Important antibiotic-resistant bacteria include Methicillin-resistant Staphylococcus aureus (MRSA) and Extended-Spectrum β-Lactamases E. coli (ESBL E. coli), These two types of bacteria can cause life-threatening diseases and poses a big problem in choosing suitable antibiotics for infections caused by them.

Antimicrobial peptides (AMPs) are considered promising antimicrobial agents that meet the required criteria for novel antimicrobial drugs. This study aims to design novel and safe AMP to be used as antimicrobial agents. In this study, an unique modified AMPs called WW-158 was designed to have a hydrophilic and hydrophobic balance using arginine to represent the cationic part and tryptophan to show the hydrophobic part. It showed good activity against MRSA with a MIC value of 35 μM. These effective concentrations were associated with negligible toxicity toward human red blood cells. Furthermore, our results showed that most of the combined groups of peptides with eight conventional antibiotics displayed synergistic modes of action or additive effects.
Regression coefficient measure of intuitionistic fuzzy graphs with application to soil selection for the best paddy crop
Authors: Akula Naveen Kumar , Basha. S Sharief
Published: May 2023

According to United Nations forecasts, India is now expected to pass China as the most populous country in the world in 2023. This is due to the fact that in 2022, China saw its first population decline in over 60 years. In order to keep pace with the rapid rise in its population, India will need to significantly raise food production in the future. Specific soil selection can help in achieving expected food production. In this article, we use Laplacian energy and regression coefficient measurements to face decision-making issues based on intuitionistic fuzzy preference relations (IFPRs). We present a novel statistical measure for evaluating the appropriate position weights of authority by computing the fuzzy evidence of IFPRs and the specific similarity grade among one distinct intuitionistic preference connection to the others. This new way of thinking bases decisions on evidence from both external and internal authorities. We evolved a statistical (regression coefficient measure) approach to determine the importance of alternatives and the best of the alternatives after integrating the weights of authority into IFPRs. This statistical analysis can be put to good use to choose the best soil for different crops to provide food for India's rapidly growing population in the future. To show how useful and realistic the suggested statistical measure is, a good example from real life is given. Additionally, we discovered how correlation and regression coefficient measurements are related to one another in intuitionistic fuzzy graphs.
Model-free control approach to uncertain Euler-Lagrange equations with a Lyapunov-based $ L_\infty $-gain analysis
Authors: Park Hae Yeon , Kim Jung Hoon
Published: May 2023

This paper considers a model-free control approach to Euler-Lagrange equations and proposes a new quantitative performance measure with its Lyapunov-based computation method. More precisely, this paper aims to solve a trajectory tracking problem for uncertain Euler-Lagrange equations by using a model-free controller with a proportional-integral-derivative (PID) control form. The $ L_\infty $-gain is evaluated for the closed-loop systems obtained through the feedback connection between the Euler-Lagrange equation and the model-free controller. To this end, the input-to-state stability (ISS) for the closed-loop systems is first established by deriving an appropriate Lyapunov function. The study further extends these arguments to develop a computational approach to determine the $ L_\infty $-gain. Finally, the theoretical validity and effectiveness of the proposed quantitative performance measure are demonstrated through a simulation of a $ 2 $-degree-of-freedom ($ 2 $-DOF) robot manipulator, which is one of the most representative examples of Euler-Lagrange equations.
Revisiting neural information, computing and linking capacity
Authors: Végh János , Berki Ádám József
Published: May 2023

Neural information theory represents a fundamental method to model dynamic relations in biological systems. However, the notion of information, its representation, its content and how it is processed are the subject of fierce debates. Since the limiting capacity of neuronal links strongly depends on how neurons are hypothesized to work, their operating modes are revisited by analyzing the differences between the results of the communication models published during the past seven decades and those of the recently developed generalization of the classical information theory. It is pointed out that the operating mode of neurons is in resemblance with an appropriate combination of the formerly hypothesized analog and digital working modes; furthermore that not only the notion of neural information and its processing must be reinterpreted. Given that the transmission channel is passive in Shannon's model, the active role of the transfer channels (the axons) may introduce further transmission limits in addition to the limits concluded from the information theory. The time-aware operating model enables us to explain why (depending on the researcher's point of view) the operation can be considered either purely analog or purely digital.

Published: May 2023

This systematic review aims to investigate recent developments in the area of arc fault detection. The rising demand for electricity and concomitant expansion of energy systems has resulted in a heightened risk of arc faults and the likelihood of related fires, presenting a matter of considerable concern. To address this challenge, this review focuses on the role of artificial intelligence (AI) in arc fault detection, with the objective of illuminating its advantages and identifying current limitations. Through a meticulous literature selection process, a total of 63 articles were included in the final analysis. The findings of this review suggest that AI plays a significant role in enhancing the accuracy and speed of detection and allowing for customization to specific types of faults in arc fault detection. Simultaneously, three major challenges were also identified, including missed and false detections, the restricted application of neural networks and the paucity of relevant data. In conclusion, AI has exhibited tremendous potential for transforming the field of arc fault detection and holds substantial promise for enhancing electrical safety.

Published: May 2023

This paper addresses the problem of scheduling $ n $ equal-processing-time jobs with release dates non-preemptively on identical machines to optimize two criteria simultaneously or hierarchically. For simultaneous optimization of total completion time (and makespan) and maximum cost, an algorithm is presented which can produce all Pareto-optimal points together with the corresponding schedules. The algorithm is then adapted to solve the hierarchical optimization of two min-max criteria, and the final schedule has a minimum total completion time and minimum makespan among the hierarchical optimal schedules. The two algorithms provided in this paper run in $ O(n^3) $ time.
Influence of Formative Online Teaching Evaluation on Autonomous Learning Ability of Students Majoring in English for Science and Technology
Authors: Sun Xuehua
Published: May 2023

The rapid development of information technology has accelerated the process of educational informatization, the level of which has also been significantly elevated. New teaching informatization modes, such as mobile terminal and online learning, can meet learners’ trans-time-and-space and personalized learning needs. As the main form of teaching evaluation, formative evaluation can provide students with timely and efficient feedback, change teachers’ teaching progress, effectively improve the teaching effect and students’ learning effect, and comprehensively promote students’ autonomous learning ability. In this study, undergraduate students majoring in English for Science and Technology (EST) in five universities of science and engineering in Xi'an city of China, were chosen as research object to explore the influence of formative evaluation (self-evaluation, peer review, and teacher evaluation) on students’ autonomous learning ability in online learning. Thereafter, the moderating effect of self-efficacy on the influence of formative evaluation on students’ autonomous learning ability was analyzed. Results showed that the Cronbach’s α coefficient value of the questionnaire designed in this study was 0.852 and the KMO value was 0.831, indicating its excellent reliability and validity. Evidently, self-evaluation and teacher evaluation can promote the improvement of autonomous learning ability. Self-efficacy plays a moderating role in the promoting effect of formative evaluation on autonomous learning ability. The effect of formative evaluation on autonomous learning ability varies significantly with its frequency of use. Conclusions in this study are of significant reference values for improving the teaching quality of EST through formative evaluation, enhancing the enthusiasm and motivation of college students, and improving the online classroom evaluation system.
Evaluation Method of College Students' Learning Autonomy Based on Social Network Support
Authors: Duan Runfang , He Xiaorui
Published: May 2023

Social network plays an important role in college students’ life. The greater the social network support they have, the more adequate social network resources they get, and the stronger their ability to cope with the challenges of study and life is. Existing studies have overemphasized the influence of social environment on college students' academic success, and have not paid special attention to the influence of the outside world on the change of college students' learning attitude. Therefore, this article studies the evaluation method of college students' learning autonomy based on social network support. Firstly, the local and global features of network nodes are extracted, and the social network roles of college students are divided. Then, a new logical structure network is constructed based on the vector representation of each node, which maximizes the influence of relevant nodes on college students' social network support. Finally, based on the new network structure, the meta-path walking algorithm is introduced to evaluate college students' learning autonomy by obtaining the attribute features supported by social networks through network nodes. Experimental results verify the effectiveness of the proposed method.

Published: May 2023

The corrections system in the United States is largely focused on punishment. Trauma-informed therapeutic services were particularly absent during the COVID-19 pandemic lockdown. This chapter discusses the importance and benefits of providing incarcerated persons with mental health treatment such as art therapy. The authors highlight one pilot study, which conducted an 8-week theme-based art therapy group in a women's county jail in Philadelphia, Pennsylvania. Participant benefits from the group correlated with three of the main goals of the incarceration system: rehabilitation, deterrence, and restoration. Participants reported multiple benefits including decreased symptoms of anxiety, depression, and feelings of isolation. A decrease in reported jail infractions among participants was also noted. The authors discuss directions for future research with this population.

Authors: Volk Liubov , Haponiuk Maksym
Published: May 2023

The necessity and scientific and methodological approaches to improving the calculation of a closed collector-drainage network of drainage systems are considered. Based on the application of the system methodology, the structure of the hierarchical and hydraulic connection between the water regime of the field and the operation mode of the closed collector-drainage network has been established. On the basis of the theoretical and experimental studies performed, relatively new scientific provisions have been proposed. This will allow, based on the application of the obtained universal equations, to construct a distribution profile of the total turbulent kinematic viscosity and the average flow velocity in the collector pipe. It becomes possible to evaluate the efficiency of the flow movement both in the constituent elements (collector pipes) and in the closed collector-drainage network as a whole. And it also becomes possible to improve the methods of designing and calculating their technological and design parameters.

Published: May 2023

The article is devoted to the actual scientific and practical problem of improving methodological and methodical approaches to the evaluation of design solutions in the water management and land reclamation industry based on the ecological and economic principles in conditions of uncertainty. To solve problems, it is necessary to reform organizational-economic relations in the industry, including new sources and forms of financing for water management and land reclamation projects, introduction of new environmentally advanced technologies, and the improvement of the existing ecological and economic evaluation of investments. Based on scientific and methodological recommendations used for evaluating the effectiveness of investment in various spheres of economic activity, the authors developed and implemented an improved methodology for the evaluation of water management and land reclamation projects. The method was tested during the reconstruction of a rice irrigation system in the steppe zone of about 3000 ha in Ukraine.

This section presents the results of the assessment of the ecological state of the river basins of the Western Polesie of Ukraine according to the level of anthropogenic load. The study was carried out based on systematic observations within the basins of small rivers, using the system model of the hierarchical structure «Basin of a small river». This model classifies the basins of small rivers according to the degree of anthropogenic loads exerted on them and makes it possible to monitor the state of the river basin according to various indicators within individual subsystems (radioactive contamination of the territory; land usage; river runoff usage; water quality). In order to improve and restore the already disturbed natural states of small river basins, a number of water protection measures have been proposed. The water management and ecological zoning of the basins of small rivers in the territory of the Western Polesie of Ukraine was carried out taking into account the quantitative and qualitative ecological and managerial indicators of the states of rivers and river basins.

This is an analysis of the state of natural waters of the Shatsk lake in the conditions of climate change. Analyzed are hydrological regime of water bodies and hydrogeological state of areas of formation and feeding. It is noted that there is a slight increase in the levels of ground and pressure aquifers, and, accordingly, surface aquifers, which is mainly due to atmospheric factors. It is noted that the chemical composition of the water of the lakes of the Shatsk group has remained stable enough for decades and the formation of its composition is determined not only by the peculiarity of the water supply of the lakes, but also by the level of anthropogenic load on the water area. It was established that in order to improve the condition and water supply of the Shatsk lake, it is necessary to develop and implement measures to prevent and minimize the possible impact of harmful effects of water, develop integrated approaches and measures to optimize water use, improve water quality, conserve and restore water resources, ensure sustainable use, and development of natural reserve fund objects.
Gamification and Player Profiles in Higher Education Professors

Published: May 2023

This paper conducts descriptive quantitative research of the player profile of a set of 808 university professors, and the player profiles that participants consider most suitable for learning when educational gamification is employed in higher education. It also studied the existence of influential variables in the chosen player profiles, including sociological (gender and age) and academic variables (area of knowledge). The results reveal that most professors are mostly explorers, followed by the socializers, and consider these player profiles as the most efficient for achieving learning objectives. There are no gaps based on sociological aspects or knowledge about gamification, but there are gaps based on area of knowledge. It is proposed that universities design training sessions for professors on educational gamification and further research on factors that influence the configuration of their player profile.
Mucocutaneous presentations of consultant critical and non-critical cases of admitted COVID-19 patients, outpatients and vaccine-associated dermatoses: a large original study of a general COVID-19 centers from Iran

Rapid and proper diagnosis of mucocutaneous presentations of COVID-19 which in many cases, are representing internal organ damages is a key way for a better approach to these patients, which could be even lifesaving. In this original study, we reported consultant critical and non-critical cases of admitted COVID-19 patients and some interesting outpatient cases during 14 months and some newly encountered vaccine-associated dermatoses. We presented 121 cases divided into 12 categories; all had full multi-aspects photographs attached as an atlas to a Supplementary File. These categories were:1- Generalized papulopustular eruptions (3 patients), 2- Erythroderma (4 patients), 3- Maculopapular lesions(16 patients), 4- Mucosal lesions (8 patients), 5- Urticarial lesions and angioedema (16 patients), 6- Vascular injuries (22 patients), 7- Vesiculobullous lesions (12 patients), 8- The specific new onset of mucocutaneous presentations or aggravation of any especial previous dermatoses (9 patients), 9- Nail changes (3 patients), 10- Hair loss (2 patients), 11- Non-specific mucocutaneous problems (16 patients) and 12-Vaccine-associated dermatoses (10 patients).In the pandemic, if we countered with extensive mucocutaneous lesions with vascular components or vesiculobullous erosive lesions in association with any cutaneous rash that could be an alarming sign of a probable life-threatening systemic event, we would need to approach them as soon as possible.

The present study analyses the ecological connectivity of four bee communities in fragmented areas in the foothills of Volcano Etna (Catania province, Sicily, Italy). The surveys were carried out in four sites under different land management regimes from 2007 to 2010. The selected areas include two different urban parks in the city of Catania (Parco Gioeni and Parco degli Ulivi), a Nature Reserve (Complesso Immacolatelle e Micio Conti, San Gregorio di Catania), and an agroecosystem (a citrus orchard, Aci Catena). The well-known bee community of a suburban park (Timpa di Leucatia, north of Catania) was considered as a control site. The bee communities include 163 species, belonging to the families Colletidae (10 species), Andrenidae (27 spp.), Halictidae (31 spp.), Melittidae (1 sp.), Megachilidae (49 spp.), and Apidae (45 spp.). Comparative zoocenotic analyses have been carried out, by calculating the main diversity indices and different methods of multivariate analysis. The ecological connectivity was evaluated through cartographic instruments by mapping the level of biopermeability of the foothills of Etna, to highlight how the level of naturality and ecological corridors could affect bee diversity. Furthermore, the degree of environmental fragmentation was evaluated through the biogeographic model of islands under the linear regression species-area, considering the examined sites as “ecological islands”. The data obtained highlight that reliable conservation strategies should consider firstly the maintenance of adequate ecological connectivity among environmental patches as well a high degree of local biodiversity, especially a high diversity of flowering plants.
