Authors: Mihajlovski Katarina , Stajcic Zeljka , Lazic Vesna
Published: September 2023

The main goal of this work was to optimize the method of processing wound dressing products (like gauzes, sanitary pads, cotton wool, compresses, and bandages) with a commercial silver colloidal solution (Koloid doo, Belgrade, Serbia) and then to examine the antimicrobial properties of the obtained items in order to potentially reach the market with new improved wound dressing products. The influence of different silver concentrations used for treatment on antimicrobial activity was investigated only against Escherichia coli. The antimicrobial activity of different types of materials treated with silver solutions of 30 ppm was investigated against Gram-negative bacteria Escherichia coli and Pseudomonas aeruginosa, Gram-positive bacteria Staphylococcus aureus, Bacillus subtilis, and Enterococcus faecalis, as well as the fungus Candida albicans. The microbial reduction of the tested materials loaded with a silver solution of 30 ppm (15-20 ?g of Ag on 1 g of fabric) against the Gram-negative bacteria E. coli and P. aeruginosa was almost maximal after 2 h of contact (i.e. 95 and 99 %, respectively). In the case of Gram-positive bacteria S. aureus, B. subtilis, and E. faecalis, a longer time is needed to completely eradicate bacteria (over 99 %). Antifungal activity testing against the fungus C. albicans gave moderate antifungal activity results.

Authors: Gök Özge , Akar Şen
Published: September 2023

In recent years, there has been a growing focus on the reuse of metallic components from waste electrical and electronic equipment (WEEE) which refers to electrical and electronic equipment that has become obsolete, stopped working, or developed defects during production. In this research, shaking table was selected as a gravity concentration tool for the recovery of copper from the light components. The flowsheet included comminution, gravimetric concentration and physical/chemical characterization of feed material and products. The process parameters were deck angle (degrees), motion frequency (Hz), wash water rate (L/m) and particle size diameter. The Box Behnken Design (BBD) was used to optimize the performance of the wet shaking table and to identify the ideal combination of its operating parameters. By analysing the experimental design, it was found that the optimal settings for deck angle, motion frequency, wash water rate and particle size diameter were 2?, 50 Hz, 12 L/m, and ?500+300 mm, respectively. These optimal settings were located near the central points of the experimental design, suggesting that the actual optimal point could be within the designed space.

OBJECTIVE

To evaluate the comparative cardiovascular effectiveness and safety of sodium–glucose cotransporter 2 inhibitors (SGLT-2is), glucagon-like peptide 1 receptor agonists (GLP-1RAs), and dipeptidyl peptidase 4 inhibitors (DPP-4is) in older adults with type 2 diabetes (T2D) across different frailty strata.

RESEARCH DESIGN AND METHODS

We performed three 1:1 propensity score–matched cohort studies, each stratified by three frailty strata, using data from Medicare beneficiaries (2013–2019) with T2D who initiated SGLT-2is, GLP-1RAs, or DPP-4is. In time-to-event analyses, we assessed the primary cardiovascular effectiveness composite outcome of acute myocardial infarction, ischemic stroke, hospitalization for heart failure, and all-cause mortality. The primary safety outcome was a composite of severe adverse events that have been linked to SGLT-2i or GLP-1RA use.

RESULTS

Compared with DPP-4is, the overall hazard ratio (HR) for the primary effectiveness outcome associated with SGLT-2is (n = 120,202 matched pairs) was 0.72 (95% CI 0.69–0.75), corresponding to an incidence rate difference (IRD) of −13.35 (95% CI −15.06 to −11.64). IRD ranged from −6.74 (95% CI −8.61 to −4.87) in nonfrail to −27.24 (95% CI −41.64 to −12.84) in frail people (P for interaction < 0.01). Consistent benefits were observed for GLP-1RAs compared with DPP-4is (n = 113,864), with an overall HR of 0.74 (95% CI 0.71–0.77) and an IRD of −15.49 (95% CI −17.46 to −13.52). IRD in the lowest frailty stratum was −7.02 (95% CI −9.23 to −4.81) and −25.88 (95% CI −38.30 to −13.46) in the highest (P for interaction < 0.01). Results for SGLT-2is versus GLP-1RAs (n = 89,865) were comparable. Severe adverse events were not more frequent with SGLT-2is or GLP-1RAs than DPP-4is.

CONCLUSIONS

SGLT-2is and GLP-1RAs safely improved cardiovascular outcomes and all-cause mortality, with the largest absolute benefits among frail people.

El tratamiento de heridas cutáneas suele enfocarse en lograr un cierre rápido y una cicatriz funcional y estéticamente satisfactoria. En el presente trabajo se evaluó la capacidad para modular el proceso de curación cutánea e inducir una regeneración, haciendo uso de un hidrogel compuesto de colágeno tipo I entrecruzado con oligouretano y recubierto con partículas de sílice coloidal. Los hidrogeles de colágeno se obtuvieron a partir de tendón de Aquiles bovino (TAB) descelularizado. Estos se entrecruzaron con prepolímero de poliuretano, y a la vez que se cargaron con sílice. Se aplicaron, como resultado de una gelificación in situ, sobre la cama de heridas cutáneas en ratas Wistar. Los resultados indicaron que después de 14 días el cierre de herida alcanzó 97.7±3.2% al usar hidrogeles que contienen sílice. Asimismo, se encontró un mayor ordenamiento de fibroblastos, incremento de matriz extracelular (ECM) madura, presencia de anexos cutáneos, neovascularización y una mayor expresión del TFG-β. Mostrando con ello una tendencia a cicatrizar más rápido que el control y el resto de los materiales. En consecuencia, estos hidrogeles podrían ser de gran utilidad en la ingeniería de tejidos suaves, en particular en el control o aceleración de la curación de heridas cutáneas

La transición de una respuesta proinflamatoria (M1) a una antiinflamatoria (M2) de macrófagos, así como su control, puede ser inducida mediante el uso de moléculas depositadas en matrices e hidrogeles. En este trabajo se presentan resultados que indican la polarización de macrófagos hacia M2 cuando las células son cultivadas sobre membranas constituidas de colágeno tipo I y entrecruzadascon oligouretanos trifuncionalizados acoplados con sílice. La secreción de TGF-β1 al medio de cultivo por macrófagos murinos de la línea RAW264.7, así como su morfología, corroboran la estimulación de la vía antiinflamatoria M2, teniendo valores con p<0.05 de significancia estadística entre los controles y las membranas basadas en colágeno. De igual manera, las propiedades fisicoquímicas del material como su capacidad de absorción de agua, resistencia a la degradación y diámetro de fibra aumentaron por efecto del entrecruzamiento. Consideramos que las propiedades biológicas y fisicoquímicas observadas hacen a nuestros materiales viables para la modulación de la respuesta inflamatoria en estudios in vivo y prometedor en el diseño de sistemas para el tratamiento de heridas crónicas, en específico las heridas de pie diabético, esto debido al ambiente altamente inflamatorio que caracteriza a la patología.

Authors: Xu Wei
Published: September 2023

The adolescent group is at the critical stage of forming ideological values. The individual’s outlook on life, deals, and worldview are gradually maturing at this stage, which must be correctly guided and scientifically educated. To maximize the role of values education for adolescents and youths and to help them develop an optimistic worldview, outlook on life, and values, we need to find the starting point of values education for adolescents. This paper attempts to establish a VAR model of the relationship between values formation and WeChat use among high school students in a city and explore the dynamic influence relationship between the two by using impulse response function and variance decomposition to get a precise result to verify the relationship, to provide some reference for values education of Chinese adolescents. It was found that with the establishment of non-traditional school papers and meeting notification channels such as school WeChat groups, adolescent students’ WeChat response rate was much faster than the standard notification response rate when teaching tasks were issued. The WeChat response rate continued to accelerate as time changed from 4~5 hours of processing time in 2015 to 0.3~0.5 hours in 2021. Teaching completion efficiency thus The efficiency of teaching completion is improved as a result. After the smoothness verification of the ADF variables, the three-time series variables of classroom education, values education, and the length of WeChat use were smooth at the 10% significance level, indicating that the relationship between the three is interrelated and the findings are credible. This further supports that using WeChat well for school education and student values calibration is reasonable and feasible.

Authors: Yu Yan
Published: September 2023

Relying on their low-cost comparative advantage, Chinese enterprises have rapidly integrated into the global industrial division of the labor system, entering the fast lane of development and becoming an important driving force behind China’s rapid economic growth. Furthermore, in recent years, this situation is changing. The cost of financing for Chinese companies has been rising yearly, a trend that has become increasingly evident, especially after the new crown epidemic. Investment growth in China’s capital markets has declined, the market has seen back-to-back years of decline, and competition has become more intense. It is imperative that enterprises need to strengthen their financial cost control management to enhance their competitiveness in the market by improving cost management. Cloud computing is a new model that relies on the Internet, with a certain amount of network storage space, scalability, and fast scaling. The development of cloud computing provides new ideas for target BPO cost management. With cloud computing, target BPO cost management becomes easier, making it a market-oriented cost control strategy for enterprises, especially those in a competitive market environment. Target BPO cost management can cover the whole process from financing to revenue through the decomposition and control of cost control objectives in various aspects. The ultimate effect is to improve the cost management level and enhance enterprise management’s efficiency. Based on the theories related to target BPO cost management at home and abroad, this paper takes 6201 listed companies in China as the object of research on cost control. The three hypotheses that financial BPO cost mitigates the company’s financial risk, financial BPO control reduces the company’s financial cost and improves the revenue of listed companies are verified by establishing a financial cost mediation effect model through nine variable control indicators. The research results show that the regression coefficient of BPO cost control construction on the revenue input of listed companies is 0.67, which obviously and effectively improves the company’s revenue ( Rd ) 13.21%; the regression coefficient of BPO cost control on financial risk (Fi) is -0.55, which reduces the financial risk of listed companies by 25.6%; the research demonstrates the necessity and feasibility of applying target BPO financial cost management for listed companies The study demonstrated the necessity and feasibility of applying target BPO financial cost management to listed companies, guaranteed the implementation of the target BPO cost management method to the ground, put forward relevant safeguard measures and suggestions for possible problems in the current application of target cost management, fundamentally solved the problem of enterprise financial cost control, and at the same time provided a guiding reference for the application of target BPO cost management in SMEs.

Published: September 2023

In recent years, the development of artificial intelligence has led to the growing influence of new media on society. The creators of digital images no longer play the role of exporters of art and culture but gradually delegate power to the audience, who are no longer passive recipients of information but are more involved in the interactive experience of video works, better engaged in the background of artworks and the emotional exchange of art and culture that occurs with artworks. Dunhuang murals, as a representative of the excellent traditional Chinese culture, have formed a wide range of cultural expressions with the help of new media technologies with different characteristics, effectively attracting audiences to participate in dissemination activities such as knowledge learning, cultural experience, and artistic exchange of Dunhuang culture. This paper provides an overview of interactive perceptual video design methods, the impact of interactive perceptual design on the narrative line of the video, and the features of the interactive perceptual invention, such as immersion, immersion, and fun. Firstly, a comparative analysis of interactive perceptual image design cases is conducted to summarize the differences between interactive perceptual image design and traditional images and outline the advantages of the former. Finally, a complete augmented reality display work is formed through the organic combination of the interactive perceptual design in three dimensions: user experience, visual guidance, and content narrative. The results of this paper show that 80% of the 120 people believe that the interactive perceptual presentation has made Dunhuang murals more vivid and exciting; 91% believe that the production of Dunhuang murals with perceptual machine technology gives visitors an immersive experience; among them, it is found through the research that visitors are 85% satisfied with this design, which exceeds the expected guesses. This paper, as a new exploration of future cases of digital communication of cultural heritage based on enhanced interactive perception technology, also argues the feasibility and effectiveness of its design in terms of results and provides new ideas for the communication of traditional culture.

Authors: Li Zhen
Published: September 2023

Exploring the heritage of Chinese traditional festival culture is to enhance the national identity of the people better. This paper introduces the classification principle of support vector machines using support vector machines as an entry point in the big data perspective and shows that support vector machines are all optimized by introducing Lagrangian functions and then finding their optimal classification decision functions. Then, the principle and steps of the artificial fish swarm algorithm are introduced and explained, and the artificial fish swarm algorithm is used to optimize the support vector machine and rank the fitness values. Finally, the AFSA-SVM algorithm is used to classify and analyze two aspects of Chinese traditional festival culture inheritance, i.e., the spiritual value and inheritance mode of Chinese traditional festival culture. From the viewpoint of spiritual value, the harmonious concept of the unity of heaven and man and the self-practice of pursuing ideals are more embodied in the Lantern Festival, accounting for 32.96% and 38.09%, respectively. Regarding inheritance methods, 61.43%, 50.15%, and 55.28% of the people use the Internet, TV, and movies to inherit traditional festivals, respectively. Based on the big data perspective, the AFSA-SVM algorithm can be used to effectively classify and analyze the cultural heritage of traditional Chinese festivals, and the data can be used better to understand the spiritual connotation of traditional Chinese festivals and enhance the sense of national identity.

The optimization path exploration of the digital education ecology of journalism and communication is to provide more comprehensive talents for journalism and communication careers. This paper explains that the SEM model is composed of two parts: measurement model and structural model, and then derives the principle equations of the SEM model and introduces the path diagram, path coefficients, and effect decomposition of the SEM model. The principle and implementation steps of the partial least squares method are then introduced to extract the principal components using orthogonal decomposition, maximize the covariance among the principal components, and then achieve the purpose of using a few variables to monitor the majority of variables. The PLS algorithm is applied to the SEM model to optimize the objective function, and multiple iterations are used to obtain the minimum residuals for all parameter estimates. Finally, the PLS-SEM model is used to analyze the data on the talent cultivation objectives and cultivation mechanism for optimizing journalism and communication digital education ecology, using the University of Z as an example. The percentages of cross-cultural, cross-media, and cross-professional in talent training objectives are 24.57%, 22.59%, and 28.58%, respectively, and the joint training of universities and enterprises in talent training mechanism increased from 7.34% in 2017 to 58.75% in 2021, which is an increase of 51.41 percentage points. The optimization of the digital education ecology of journalism and communication based on the PLS-SEM model should focus on the joint development of schools and enterprises and pay attention to the all-around curriculum training.

With the accelerated advancement of big data Internet development, people gradually realize the urgency and importance of energy saving, so the multi-objective optimization research for the performance of office buildings in cold regions is significant, and this paper focuses on the construction of a building window design model based on visual comfort supported by multi-objective evolutionary algorithm- taking office buildings in cold regions as an example, firstly, by reviewing the literature to understand the principle, algorithm, and concept of multi-objective evolution, construct the building window design model based on visual comfort according to the objective function and extract the standard model of inner corridor slab space building in office buildings in cold regions of Harbin and Shenyang. The optimized design of building window parameters was carried out using the established joint simulation and optimization work platform. The results show that for Harbin, as the window heat transfer coefficient increases, the heating energy consumption increases, the cooling energy consumption increases more slowly, and the total energy consumption increases linearly. An increase in window heat transfer coefficient by 0.1W/ (m
2 ∙K) Increases are cooling energy consumption by 0.18%, heating energy consumption by 0.78%, and total energy consumption by 0.46%. For Shenyang, as the window heat transfer coefficient increases, the heating energy consumption increases, the cooling energy consumption increases more slowly, and the total energy consumption increases linearly. If the heat transfer coefficient of the window increases by 0.1W/ (m
2 ∙K), cooling energy consumption increases by 0.18%, heating energy consumption increases by 0.78%, and total energy consumption increases by 0.46%. This study provides a theoretical basis for extracting standard models for other building types while making the results more generalizable and improving the efficiency of sustainable office building design.

Published: September 2023

With the development of network technology, the convenience and flexibility of smart education have made it right to meet the needs of teachers’ professional development, which has led to its rapid development. As traditional smart campus data networks suffer from long construction periods, high costs, and poor flexibility of wired networks, existing wireless networks may suffer from audio delays, lagging, and other problems. Now with the addition of 5G networks, it is not only able to provide a new design concept and teaching method for modern teaching, but it is also of great significance to improve the comprehensive strength of schools and accelerate the construction and implementation of teacher support service models. In this paper, we investigate URLLC and eMBB multiplexing mechanisms in 5G, introduce the signal space diversity technique based on rotational modulation, and propose SSD-based URLLC and eMBB multiplexing mechanisms. The SSD-based URLLC and eMBB multiplexing mechanisms are validated through downlink-level simulations. The results show that the BER is improved by about 1.0dB at 10-6 orders of magnitude, and the BER is improved by about 1.0dB at 10-3 orders of magnitude under the simulation verification of the Rayleigh channel compared to the case without spatial diversity. In the simulation of the spatial diversity multiplexing mechanism of the TDL-A-1000 channel, the BER is improved by about 1.5dB at 10-6 orders of magnitude, and the BER is also improved by about 1.5dB at 10-3 orders of magnitude compared with the case without spatial diversity. In summary, the SSD-based multiplexing mechanism proposed in this paper can reduce data BER, improve data transmission reliability, and make the construction and implementation of the teacher support services model in smart education faster and more convenient.

Tax governance faces more complex challenges with the deepening integration between traditional industries and the digital economy. This paper analyzes the main features of the digital economy according to its development, measures the digital economy based on the mixed-frequency data sampling method, and studies the selection method of the weight function and the change of the shape of the weight function with the parameters through the exploration of parameter estimation. Meanwhile, the MF-VAR model combining vector autoregression is proposed for the characteristics of mixed-frequency data. Then, the MF-VAR model is used to measure the tax leakage of the digital economy from 2015 to 2019 and compare its tax rate with that of major economies worldwide. The VAT of e-commerce e-tailing in 2019 is measured to be 848.15 billion yuan, accounting for 4.97% of the annual tax revenue, and the personal income tax leakage is measured to be 141.25 billion yuan, accounting for The amount of VAT, and personal income tax loss from e-commerce and their proportion of annual tax revenue increased year by year from 2015 to 2019, with an average annual growth rate of 40.58% and 25.21%, respectively. Tax authorities should change the traditional thinking of levy and administration, respond to the changes of the times, and innovate the governance system to protect the digital economy model in its primary stage, but also bring its development into the rule of law and standardization.
