Authors: Luo Dianwen
Published: October 2023

The application of VR technology to the teaching of college Ideology and politics classes not only brings new opportunities for college education innovation but also innovates the Ideology and politics teaching mode. This paper first introduces the principle of image acquisition and the presentation of virtual reality technology. After determining the parameters of left and right viewpoints, the scene images are acquired through graphic rendering technology, and then the final synthesis of left and right images is carried out. Then the determination of the comfort zone of the stereo display is introduced, using the correspondence between stereo depth and γ to determine the comfort zone. Finally, the effect of virtual reality devices in practical teaching of Ideology and politics is analyzed in terms of student performance, students’ perceived usefulness, satisfaction, and classroom acceptance of VR devices. Regarding perceived usefulness, 41% of students strongly agreed, and 30% agreed with the question, “I think the technology provides a better virtual learning scene”. The integration of VR technology into the practical teaching of Ideology and politics in higher education institutions has broken through the traditional teaching mode of Ideology and politics in higher education and improved the experience of Ideology and politics in higher education.

Published: October 2023

With high renewable energy sources (RESs) penetration in distribution networks, handling the uncertainties of RESs outputs and multi-time coupling problems in the dynamic network reconfiguration (DNR) is a big challenge. Besides, the existing mathematical and artificial intelligence algorithms for network reconfiguration face the problem of falling into local optima and poor convergence. To address the above challenge and problem, this paper first establishes a chance-constrained programming model to handle the uncertainties. Then the Minty algorithm is applied for efficiency and accurate static network reconfiguration (SNR) in each time interval. Finally, a branch exchange-based method is proposed to eliminate violations for the operation times of switches. Numerical simulations on the IEEE 33 system and an actual 151-bus distribution network show the superiority of the proposed algorithm over existing methods.

Authors: Jiang Congshi , Chen Quan
Published: October 2023

The characteristics of data aggregation with different network environments and dynamic changes in channel availability make some problems in IoT data aggregation. Therefore, this paper proposes an FMA-coverage model for algorithm design based on edge information. The FMA-coverage model includes the method of edge frequency, the method of primitive length (stroke), the texture energy metric of Laws and the method of fractal texture description. The FMA-coverage model can improve the network performance of IoT data aggregation. From the computational analysis, it can be seen that the security of data storage is only 17%. After the improvement of the fast matching algorithm, the security is up to 87%. After the network coding scheme, the IoT performance of data aggregation is up to 95%. It is important to note that, in this case, the required transmission volume in the network can be greatly reduced when the links are long. The IoT performance is up to 97% with the compression-aware scheme. By cross-sectional comparison, the IoT-based mobile model has the highest accuracy, with 98% accuracy of data aggregation. This paper extends the data aggregation mechanism by introducing fast-matching algorithms for device authentication and secure storage.

Authors: Zhang Luyang , Liu Dashun
Published: October 2023

Significant corrosion problems in materials related to marine engineering projects are bound to be a threat to overall operational safety and reliability. This paper investigates the influence of corrosion time on the material product film performance and its corrosion resistance, combined with the function integral algorithm. The gray matrix transform, image binarization, and wavelet transform of the function integral algorithm are used to establish the corrosion damage image recognition model and quantify the microscopic characteristics of corrosion damage based on the corrosion morphological features. Through the corrosion damage image recognition model, evaluation and analysis of common marine engineering materials 2205 duplex stainless steel and Q420 steel in chloride ion (Cl−). Test results show that: chloride ion on 2205 duplex stainless steel corrosion resistance 17.89μA cm−2 was the critical point, the higher the concentration played a suppressive effect. Chloride ions on Q420 steel corrosion resistance in lower solutions below 2.23μA cm−2 concentration, Q420 surface product film has a certain protective effect on the substrate. The corrosion characteristic value evaluation results based on the function integration algorithm are consistent with the electrochemical test results, so the evaluation model established in this paper can effectively evaluate the corrosion resistance of the material.

Published: October 2023

The rapidly developing big data technology not only directly affects people’s work and life but also plays a greater role in promoting the direction of education. This paper introduces online teaching methods to traditional teaching methods, constituting a hybrid online and offline teaching method, and optimizes the reform of business English teaching objectives, contents and processes. After pre-processing the teaching evaluation indexes, the rough set method based on big data technology is used to mine the association rules of teaching data. The principal component analysis evaluation method was used to evaluate the structure of the mined teaching data set. And the changes in teaching evaluation index values obtained by the principal component analysis method were used as the basis for determining the effectiveness of the business English teaching reform. The experiment proved that: aS10 students in group A with the worst business English level increased their teaching level value from 1.004 to 1.224 after the general reform, an increase of 20.77%. After the online and offline hybrid reform, the teaching level value increased from 1.004 to 1.306, an increase of 22.72%. This shows that the reformed business English teaching mode has deepened the reform and innovation of business English teaching through the full use of big data technology, improved the comprehensive English ability and literacy of the majority of students, and laid a solid foundation for the future development of students’ working career.
Combining big data with innovative education on online ideology and politics for college students
Authors: Fan Qi
Published: October 2023

This paper proposes new methods and approaches to online ideological and political education for college students. Firstly, a network ideological and political intelligence platform is constructed based on the functional stratification characteristics of big data. Then, the ideological and political contents are clustered and filtered, and the contents are divided into several teaching fields according to the nature of various events. Based on this, the “incentive compatibility” mechanism based on “interest cluster” analysis is used to cluster and model users interested in the topic, to recommend relevant online content to similar groups. Finally, we analyzed the problems of online ideological and political education in colleges and universities in China and proposed countermeasures. Only 52.3% of colleges and universities have substantial recognition of the construction work results. 75% of the first batch of pilot colleges and universities have funding sources with the Ministry of Education and the schools themselves, 45% of colleges and universities have special funds of over 1 million, and the remaining 55% have special funds below 200,000. For further improvement, college students’ online ideological and political construction needs to be paid attention to and carried out.

Authors: Shen Jing , Ling Sheng
Published: October 2023

Various exquisite graphic designs that can be seen everywhere beautify people’s vision and influence people’s visual aesthetics subtly. This paper starts with the visual aesthetic elements of graphic design and discusses the construction of visual aesthetic element systems in graphic design by analyzing the composition elements and aesthetic characteristics. Secondly, it proposes to use the biological visual perceptual machine model to process information through two visual pathways in a hierarchical manner. The features of graphic design images are expressed, stored, and extracted using the visual information model. Finally, the effectiveness of the bio-visual perceptual model applied to the construction of visual aesthetic elements of graphic design is verified by the Caltech5 database, Caltech256 database, and Scene15 database. The results show that the classification accuracy of the bio-visual perceptron model is 94.28%, 91.36%, and 99.75% in Caltech5, Caltech256, and Scene15 databases, respectively, which is 23.12% higher than the accuracy of other neural network models on average. The bio-visual perceptron model proposed in this paper can accurately detect the elemental features in complex graphic design, which provides a new idea and method for rapid detection and recognition for graphic design workers.

Published: October 2023

Mordants are materials used to fix long periods of colour on selected fabrics or fibres. The current research aimed to dye natural fibres like palm leaf (Borassus flabellifer L.), korai grass (Cyperus pangorei L.), banana fibre (Musa accuminata L.), screw fine fibre (Pandanus), sisal fibre (Agave sisalana Perrine), and pineapple fibres (Ananas comosus L.) with Calendula officinalis plant flower dye. The dye was fixed to the selected fibre material with the help of different mordants. The Calendula officinalis flower dye produced different colours, like black, brown, orange, sandal, yellow, etc., on the dyed materials. The different colour formations on the dyed materials are based on the mordents used to fix the dye. The mordants tonify the different colours in the same dyestuff of Calendula officinalis flower dye. Mordant-based dyed natural fibres have good fastness properties against light and water. Calendula officinalis dyes have potential activity against the skin infection-causing organism Pseudomonas aeruginosa.

Published: October 2023

This study focused on antibiotic resistance genes as emerging contaminants with potential global human health implications. Intensive livestock farming has been identified as a major contributor to the spread of resistant bacteria and genes. The study examined antimicrobial-resistant Escherichia coli and tetracycline-resistant genes in raw milk from commercial dairy farms in Kano State. Out of 300 registered farms, 54 (18 %) were purposively sampled for the study. A total of 313 milk samples were collected and processed through enrichment and inoculation on selective media for Escherichia coli isolation. The antibiogram pattern of the isolated Escherichia coli strains was assessed using the disk diffusion method. The results revealed resistance to various antimicrobial agents, with no resistance to quinolones but high resistance to ampicillin (100 %), erythromycin (73.3 %), and tetracycline (46.7 %), among others. The multiplex polymer-ase chain reaction was conducted on all Escherichia coli isolates to detect tet genes (tet A, B, C, D, and M), and one isolate carried the tet M resistance gene, while six (40 %) others carried the tet A resistance gene. The study concludes that a significant proportion of the cultured Escherichia coli strains were resistant to one or more tested antibiotics, indicating a potential public health threat associated with Escherichia coli contamination in raw milk. We recommend implementing robust regulatory policies governing the use and sales of antimicrobials in animal production. Furthermore, we suggest further investigation into other resistant genes that these isolates might carry to better understand the extent of antibiotic resistance in the region.

Published: October 2023

The mammalian pineal gland is a structure that in recent years has been extensively studied, due to its functions and the hormones it produces. Bats are the only known flying mammals, with the order having a large number of species. This study was carried out to investigate the gross and histological features of the pineal gland of the Eidolon helvum, the African fruit bat, using male and female subjects. Eight free flying E. helvum (4 males, 4 females) were captured using mist nets. The pineal gland was grossly observed to be very small in size, oval in shape, and covered by the pia mater. Histological examination revealed two populations of pinealocytes – Types I and II – oval structures possessing acidophilic cytoplasm and large, round nuclei. Pinealocytes were seen to appear singly or in clusters, having no particular arrangement. Sexual dimorphism was observed, with the females having less density in population of pinealocytes at the peripheral region of the gland. This was consistent in all subjects examined. Astrocytic appearance was typical with long and slender processes, and perivascular and capsular microglia were observed. The glia cells were observed to be abundant in the parenchyma and around the capsule. There was no sensitivity to NeuN antibody. Results obtained may find application in behavioural and comparative neuroscience.

Authors: Kosten Mehmet Muzaffer , Emlek Alper , Yildiz Recep , Barut Murat
Published: October 2023

In this study, a long short-term memory (LSTM) based estimator using rotating axis components of the stator voltages and currents as inputs is designed to perform estimations of rotor mechanical speed and load torque values of the induction motor (IM) for electrical vehicle (EV) applications. For this aim, first of all, an indirect vector controlled IM drive is implemented in simulation to collect both training and test datasets. After the initial training, a fine-tuning process is applied to increase the robustness of the proposed LSTM network. Furthermore, the LSTM parameters, layer size, and hidden size are also optimised to increase the estimation performance. The proposed LSTM network is tested under two different challenging scenarios including the operation of the IM with linear and step-like load torque changes in a single direction and in both directions. To force the proposed LSTM network, it is also tested under the variation of stator and rotor resistances for the both-direction scenario. The obtained results confirm the highly satisfactory estimation performance of the proposed LSTM network and its applicability for the EV applications of the IMs.
Editorial Gatekeeping in Sports News During Prime Time Television in a Public Broadcaster
Authors: Cruz Carla , Araújo Duarte
Published: October 2023

Introduction.Based on Shoemaker's model of gatekeeping, this study addresses two questions: What social representations of sports are promoted by the prime time news program of the public television broadcaster Radio Televisão Portuguesa (RTP)? How do editors assess sports news stories during the editorial decision-making process?

Material and Methods.For this, we quantitatively examined all the sports content in the prime time ‘Telejornal’ daily news program of RTP during a trimester. Moreover, we studied the factors that influenced editorial decisions, by conducting naturalistic participant observation and semi-structured interviews.

Results.Results indicate that facts of greater public protagonism, which cause a significant emotional reaction and are relatable to the public, are more newsworthy. The main constraints influencing the editorial decisions were organized in three co-dependent areas: Social System (macro level), RTP Organization (meso level) and Telejornal Newsroom (micro level).

Conclusions.Findings contribute to a reduction in social stereotypes created by television broadcasters, and to sports actors optimizing their communication strategy.

Introduction.Fundamental motor skills (FMS) are a critical component of success in various sports and lifelong physical activity (PA). This study aimed to evaluate and compare the FMS proficiency levels of 7-9-year-old children from Poland and Latvia, providing insights into the current state of motor competence in these populations.

Material and Methods.A cross-sectional study design was utilized, incorporating a sample of 163 boys and girls. The FUS test (Fundamental Motor Skills in Sport), a comprehensive, qualitative, and process-oriented assessment tool was used to assess FMS. The FUS test encompassed a range of movement tasks, including hurdles, jumping rope, forward roll, ball bouncing, ball throwing and catching, and kicking and stopping a ball that allows for a thorough evaluation of FMS proficiency.

Results.The study revealed alarmingly low FMS proficiency levels in both countries, with 93.3% of students displaying ‘insufficient FMS proficiency’. The Mann-Whitney U test showed that Latvian boys outperformed their Polish peers in jumping rope and forward roll (p < 0.05), while Polish boys exhibited superior results in kicking and stopping a ball (p < 0.05). In contrast, Polish girls achieved significantly higher scores in hurdles and kicking and stopping a ball (p < 0.05) compared to Latvian girls, who scored higher in jumping rope (p < 0.05).

Conclusions.These findings highlight the urgent need for effective, evidence-based interventions to improve motor competence in both countries, emphasizing the importance of incorporating FMS development into physical education curricula and promoting regular PA for children.
A rare cause of mixed hypertrophic and dilated phenotype cardiomyopathy – the MELAS syndrome

Published: October 2023

Introduction

MELAS is a systemic hereditary condition that can present as hypertrophic or mixed hypertrophic and dilated phenotype cardiomyopathy in young individuals, although a late-onset form is also described in the literature. Genetic testing is essential for correct diagnosis and appropriate management.

Case presentation

We present the case of a 22-year-old male who was referred to our center after being diagnosed with NYHA class III heart failure with a mixed hypertrophic and dilated cardiomyopathy. His medical history included stroke episodes, seizures, progressive hypoacusis, neurocognitive impairment, and muscle atrophy. Lactic acidosis and elevated CK levels were also noted. The ECG revealed short PR interval and delta wave in lateral leads. TTE showed mildly dilated and hypertrophied LV and RV with severe biventricular systolic impairment. The CMR study was relevant for ring-like subepicardial fibrosis, predominantly in the medium and apical segments. Brain MRI showed multifocal supratentorial subcortical stroke-like lesions in both cerebral hemispheres, involving multiple vascular territories and following a migratory pattern. Genetic testing confirmed a pathogenic MT-TL1 mutation (m.324A>G) and the patient was diagnosed with MELAS. Further management included specific lifestyle recommendations and cascade genetic screening, as well as starting GDMT for HFrEF. Three months after discharge, his clinical status improved. However, the LVEF remained reduced. After careful consideration, an ICD was implanted for primary prevention.

Conclusion

A red-flag approach in this young patient, which took into consideration the stroke-like episodes, lactic acidosis, seizures, hypoacusis, myopathy, as well as the short PR interval, led to the correct diagnosis, further confirmed by using the appropriate genetic test. Failure to diagnose affects the patient’s prognosis, as their prognosis and clinical status are influenced by enforcing specific recommendations.
Hero’s Journey in Korean Confucian Historiography: Biographies of Kim Yusin and Kungye in the Context of J . Campbell’s Monomyth
Authors: Solovyov A. V.
Published: October 2023

For the first time in Russian (and world) Korean studies, biographies of real historical characters are analyzed within the framework of the concept of monomyth (or hero's journey) coined by Joseph Campbell. Previously, such an approach was practiced only in the study of narrative prose. This paper focuses on practical evaluation of monomyth as a prism with regard to Confucian chronicles. Critical analysis of the text showed us to conclude that the concept of monomyth is quite suitable — with some reservations — for describing the historical narrative of the biographical section of the Confucian chronicle Samguk sagi (Historical Record of the Three Kingdoms). The research revealed life paths of the chosen hero, who embodies the ideal of a loyal subject, and his antagonist generally follow the three-part model proposed by Campbell (departure — initiation — return). This allows us to conclude that a powerful autochthonous Korean cultural stratum contributed to the formation of a specific syncretic worldview in Korea during the Three States and United Silla period (traditional dates: 1st century B.C. — 10th century A.D.), which integrated Confucianism, Buddhism and Taoism into a single system and was reflected in the official chronicle compiled in the 12th century. The Confucian historiographer's representation of these substrates (given a certain ability of these teachings to assimilate each other's concepts) was cemented by myth, which, together with the Confucian canon, set the principles of text organization, plot models, and ways of presenting historical events. The susceptibility of Korean Confucianism at this historical stage to mythology allowed mythological cosmology to integrate quite easily into the Confucian world-building narrative, and to deal with subjects that were previously considered taboo for Confucian ethics in classical Orientalism, such as the manifestations of the Oedipus complex. The interpretation of history as a moral and ethical drama brings official Confucian historiography closer to political myth in its modern interpretation and allows us to evaluate the historical text in a new way.

Authors: Ovchinnikov V. M.
Published: October 2023

The article explores the possibilities and prospects of using an audio visualized (multimedia) text, which, according to the author, is the phenomenon of a computer game (in particular, the genre of global strategy) to represent the historical process in the form of its simulation. The study aims to identify the possibilities and limitations of demonstrating elements of world-system analysis in the space of the game universe of global historical strategies. The goals are: 1) to analyze key aspects of virtualized game simulation in the form of global strategy; 2) to systematize characteristic features of the combination of scientific and subjective factors in game simulation; 3) to identify the influence of the cultural factor on creating virtual worlds in games; 4) to conduct case-studies considering games through the prism of the theoretical framework of game simulation. The study employs the historical-genetic method and discourse analysis. Axiological and anthropological approaches are used to find sociocultural specificities of game simulations by investigating their value orientations and practices in the game and in the community of gamers. The study specifies features of variable modelling on the example of game universes of Civilization, Crusader Kings, Europa Universalis etc. The results of the study include the analysis of 1) history reconstruction in global game strategies from the point of view of philosophy of culture; 2) game mechanics reflecting their creators’ and gamers’ personal features; 3) creating cultural landscape in global simulation games. The author suggests that modern global strategies is not only a kind of virtual entertainment and cybertext, but also a means of reliving the historical narrative when mass consciousness can explore alternative history. This approach makes way for spreading historical knowledge via historical simulation.

Published: October 2023

Dissolved organic matter (DOM), which is part of of natural organic matter or NOM, contained of carbon compound and can cause problems related to taste, odor, and disinfection by-products (DBPs) in water and treated water. Permanganate is strong oxidant and have been know its efficiency in oxidazing organic compound. Coagulation is most widely used in all water treatment plant due to its efficiency in removing suspended solid. The objectives of this study is to characterize and to remove natural organic matter in term of Â DOMÂ  in water through KMnO4 preoxidation, Al2(SO4)3 or FeCl3 coagulation, KMnO4 preoxidation followed by Al2(SO4)3 or FeCl3 coagulation. Raw water, which was taken from Jagir River in Surabaya, and treated water were measured quantitatively by using total organic carbon (TOC), ultraviolet at wavelength 254 nm (UV254) in order to know its aromatic properties. In addition, fourier transfor m infrared spectroscopy (FTIR) was used to identify the functional group of DOM in water and treated water. The results showed that raw water has high TOC concentration (6,9 mg/L) and mainly composed of aromatic (UV254 0.075 cm-1). The optimum result showed that TOC concentration and UV254 removed significantly into 4,2 mg/L and 0,0020 cm-1, respectively after preoxidation followed by FeCl3 coagulation. According to FTIR analysis, mostly single bond carbon such as C-O and C-H still exist in treated water. This results indicated that preoxidation-coagulation has a better performance than preoxidation only and coagulation only.

Biodegradable plastic is a type of plastic that can be broken down by microorganisms into water and carbon dioxide gas as its final products after it has been used and disposed of in the environment, without leaving behind any toxic residue. Due to its ability to return to nature, biodegradable plastic is considered an environmentally friendly material. Cassava peel, obtained from cassava plant products (Manihot Esculenta Cranz), is a major food waste in developing countries. As the cassava cultivation area expands, it is expected that the production of cassava tubers will increase, resulting in a higher amount of cassava peel waste. Typically, every kilogram of cassava can produce approximately 20% cassava peel waste. The relatively high starch content in cassava peel makes it suitable for the production of biodegradable plastic films.Keywords: Bioplastic, Biodegradable, Cassava Starch, Biotechnology.Â ABSTRAKÂ Plastik biodegradabel adalah plastik yang dapat terurai oleh aktivitas mikroorganisme menjadi hasil akhir berupa air dan gas karbondioksida, setelah habis terpakai dan dibuang ke lingkungan tanpa meninggalkan sisa yang beracun.

This research aims to examine the influence of intangible assets, financial flexibility, green innovation, and human capital on sustainable growth of companies, with firm size and return on assets (ROA) as control variables. The study uses a sample of 136 high-profile companies from the period of 2018 to 2021, with total of 544 observations. Through descriptive statistical tests, panel data model testing, hypothesis testing, and multiple linear regression analysis, the findings of this study indicate that intangible assets and financial flexibility have a positive effect on sustainable growth. However, green innovation and human capital have a negative impact on sustainable growth of companies. These results suggest that valuable intangible assets and good financial flexibility contribute to enhancing sustainable growth, whereas high levels of green innovation and human capital may not always have a positive impact on sustainable growth. Further research is recommended to understand the reasons why green innovation and human capital have a negative influence on the sustainable growth of companies.
Social management: impact or interaction?
Authors: Kremnyov Evgeny Vladimirovich
Published: October 2023

The subject of this paper is the system of social management, in relation to which the author attempts to identify basic strategies for combining different types of links (vertical and horizontal) and relations (impact and interaction) of this system in the context of the growing demand of society for participation in social management. The theoretical and methodological basis for the study of this subject is the concept of E. Mayo and his followers about the social orientation of management and the system-modeling approach. The specificity of the social system is that the effectiveness of each of the identified strategies should be evaluated within the framework of regional conditions in which it is formed. Based on the understanding of social management as a system, the elements of this system, types of links and relations within it are described. The scientific novelty of the work lies in the fact that it describes for the first time the identified strategies of combining these links and relations: horizontal-interacting, vertical-interacting and horizontal-impacting. The results can be used for planning strategies of interaction with different regional systems of social governance of different levels. The article concludes that social governance as a concept has prospects for development, since its basic task is to satisfy the socium's request for joint regulation of social processes.
