Authors: Yu Junxia , Mu Jie
Published: September 2022

First aid is to give immediate first aid to patients who have suffered accidental injuries or sudden diseases before the emergency medical personnel arrive at the scene or are sent to the hospital for treatment; myocardial infarction is a severe and emergency of coronary heart disease. It is often because of coronary atherosclerosis, plaque rupture, bleeding, or thrombosis, which leads to the acute and complete occlusion of the coronary arteries and acute necrosis of the myocardium. This article aims to investigate the effectiveness of a stratified emergency care team assisted by multidisciplinary first aid knowledge in acute myocardial infarction first aid, hoping to reduce the probability of acute myocardial infarction through first aid and nursing care. Business process reengineering is a management idea that reached its heyday in the 1990s and is usually defined as achieving workflow and productivity through the reorganization and optimization of corporate strategies, value‐added operational processes, and the systems, policies, organizations, and structures that support them. This article first outlines the concepts and steps of medical image registration, analyzes the characteristics of current medical image registration methods, and uses the two most commonly used medical registration methods today; in this study, the BPR theory was used to construct the AMI emergency care process in the hospital, which effectively reduced the emergency delay time of AMI patients, improved the patient’s emergency response, and increased the efficiency of emergency nurses’ rescue work. The experimental results in this paper show that the sensitivities of the first four groups of ST↑III > II, ST ↓ aVL > I, STV3 ↓ /STIII↑≤1.2, STI ↓ ≥0.05 mV are 82.1%, 80%, 75.3%, and 60.3%, respectively. Their sensitivities are relatively close, both are greater than 50%; among them, ST↑III > II has the highest sensitivity, which is 80%. In terms of specificity, ST↑III > II, ST ↓ aVL > I, STV3 ↓ /STIII↑≤1.2, and STI ↓ ≥0.05 mV were 82.1%, 89.2%, 82.7%, and 65.2%, respectively. ST ↓ ≥0.05 mV has the lowest specificity, and ST ↓ aVL > I has the highest specificity.

Published: September 2022

With the rapid development and application of artificial intelligence technology, medical data play an increasingly important role in the medical field. However, there are privacy protection and data ownership issues in the process of data sharing, which brings difficulties to machine learning and data mining. On the one hand, for fear that they may risk being held accountable by users or even breaking the law due to these issues, healthcare providers are reluctant to share medical data. On the other hand, users are also reluctant to share medical data due to the possibility of privacy disclosure in the data sharing process. To improve the security and privacy of shared medical data, we propose a user-centered medical data sharing scheme for privacy-preserving machine learning. Our solution combines blockchain and a trusted execution environment to ensure that adversaries cannot steal the ownership and control of user data during sharing. A blockchain-based noninteractive key sharing scheme is proposed that allows only the users and the TEE to decrypt the shared data. At the same time, we design an auditing mechanism to facilitate users to audit the sharing process. The security analysis shows that the scheme ensures the privacy and security of user data during storage and sharing. We have completed simulation experiments to demonstrate the effectiveness and efficiency of our scheme.
The Establishment of College Student Employment Guidance System Integrating Artificial Intelligence and Civic Education
Authors: Huang Li
Published: September 2022

A logical and appropriate job advising system for college students is the only way to address the current dire work scenario for recent graduates in a society that is becoming more and more competitive. The process of building new career advice systems for college students is still fraught with many major issues. Existing problems are manifested in the lack of a perfect employment guidance system for college students and a lack of effective ideological and political education, which leads to the inability of college students to establish a correct employment concept. At the same time, the recommendation method used in the current college student employment guidance system is not reasonable enough and only considers students’ one-way preference for employment units. Then, the history of one user’s employment is likely to lead to unreliable negative samples, which affects the recommendation performance. In addition, the current employment recommendation system cannot fully integrate the service function, management function, education function, and research function of the employment guidance system. In this paper, we address the aforementioned issues and propose an unique career counseling system for college students by combining algorithmic recommendation with ideological and political education. The system adaptively aggregates the preferences and needs of students and employers and fully integrates several functions of the student career competence and career guidance system. The experimental results show that the establishment of a college students’ employment guidance system integrating artificial intelligence (AI) and civic education not only has better interpretability compared with the traditional employment guidance system but also has a higher area under curve (AUC). Furthermore, we also discuss the importance of ideological and political education and referral systems in the work of the career guidance system through ablation experiments. The results show that the AUC values of integrating ideological and political education and recommender systems were higher than those of integrating only ideological and political education or recommender systems. Therefore, establishing an employment guidance system for college students that integrates AI and civic education can effectively guide students’ employment. At the same time, the college student employment guidance system proposed in this paper can offer employment guidance courses in colleges and universities, help graduates to solve their doubts, and make graduates adjust their psychological state in the process of job hunting.

Authors: Ni Jianjun , Tang Guangyi , Shen Tong , Cai Yu , Cao Weidong
Published: September 2022

Sequential recommendation algorithm can predict the next action of a user by modeling the user’s interaction sequence with an item. However, most sequential recommendation models only consider the absolute positions of items in the sequence, ignoring the time interval information between items, and cannot effectively mine user preference changes. In addition, existing models perform poorly on sparse data sets, which make a poor prediction effect for short sequences. To address the above problems, an improved sequential recommendation algorithm based on short‐sequence enhancement and temporal self‐attention mechanism is proposed in this paper. In the proposed algorithm, a backward prediction model is trained first, to predict the prior items in the user sequence. Then, the reverse prediction model is used to generate a batch of pseudo‐historical items before the initial items of the short sequence, to achieve the goal of enhancing the short sequence. Finally, the absolute position information and time interval information of the user sequence are modeled, and a time‐aware self‐attention model is adopted to predict the user’s next action and generate a recommendation list. Various experiments are conducted on two public data sets. The experimental results show that the method proposed in this paper has excellent performance on both dense and sparse data sets, and its effect is better than that of the state of the art.

Published: September 2022

Construction cost estimation is one of the essential processes in construction management. Project cost is a complex engineering problem due to various factors affecting the construction industry. Accurate cost estimation is important in construction management and significantly impacts project performance. Artificial intelligence (AI) models have been effectively implemented in construction management studies in recent years owing to their capability to deal with complex problems. In this research, extreme gradient boosting is developed as an advanced input selector algorithm and coupled with three AI models, including random forest (RF), artificial neural network (ANN), and support vector machine (SVM) for cost estimation. Datasets were gathered based on a survey conducted on 90 building projects in Iraq. Statistical indicators and graphical methods were used to evaluate the developed models. Several input predictors were used, and XGBoost highlighted inflation as the most crucial parameter. The results indicated that the best prediction was attained by XGBoost‐RF using six input parameters, with r‐squared and the mean absolute percentage error equal to 0.87 and 0.25, respectively. The comparison results revealed that all AI models showed good prediction performance when applied to datasets affected by more than two parameters. The outcomes of this research revealed an optimistic strategy that can help decision makers select the influencing parameters in the early phases of project management. Also, developing a prediction model with high precision results can assist the project’s estimators in decreasing the errors in the cost estimation process.

Authors: Salahou Mohamed Khaled , Chen Xiaoyuan , Zhang Yupeng , Jiao Xiyun , Lü Haishen
Published: September 2022

Field-scale estimation of soil hydraulic parameters is important for simulating water movement, particularly in the vadose zone. The accuracy of soil hydraulic parameters significantly affects the output of models using these parameters as input variables. A new approach for an inverse method, often referred to as inverse modelling, was presented to calibrate soil hydraulic parameters. The new method is based on the use of uniform design theory to generate uncertainty estimates of the soil hydraulic parameters. The uncalibrated and calibrated soil hydraulic parameters were evaluated by comparing the predicted and measured soil water contents using the HYDRUS-1D model. The results show that the calibrated soil hydraulic parameters that were inversely estimated by uniform design theory were accurate and reasonable. In addition, the results provided recommendations for improving the estimation of soil hydraulic parameters when there are no available observation data for calibrating and optimizing soil hydraulic parameters.

Published: September 2022

Objective. The dysfunction of immune surveillance, a hot spot in cancer research, could lead to the occurrence and development in multicancers. However, the potential mechanisms of immunity in Wilms’ tumor (WT) remain unclear on Wilms’ tumor (WT). In this study, we aim to investigate the immune cell in WT and explore the underlying treatment strategy. Method. We quantified stromal and immune scores by using ESTIMATE algorithm based on gene expression matrix of WT patients in TCGA and GEO databases. Different expression genes (DEGs) and functional enrichments were analyzed by R studio and DAVID tools. Flow cytometry, immunofluorescence staining, ELISA assay, and qRT-PCR were used for detecting the NK cells, cytotoxic cytokines (INF-γ, PRF, and GZMB), and NK cell receptor expression, respectively. WT patient autologous NK cells were stimulated by IL-2 and IL-15, and the cytotoxicity of NK cells against WT cell lines was detected by LDH assay. Western blot experiment was used for measuring the MAPK signaling pathway protein maker in NK cells. Results. ESTIMATE indicated that WT tissue had a lower immune score than adjacent kidney tissue. Meanwhile, the low immune score group was associated with poorly outcomes. DEG functional enrichment analysis showed that NK cell-mediated cytotoxicity was significantly different in low and high immune score groups. Although few of proportion of NK cells in WT patients were increased, most of that were significantly lower than normal children. Moreover, the proportion of NK cells and the expression level of INF-γ, PRF, and GZMB in WT tissue were lower than adjacent kidney tissue. Importantly, the NKG2D expression level of NK cells was significantly lower in WT tissue. Furthermore, in vitro, compared with uncultured NK cells, IL-2 and IL-15 could effectively enhance the cytotoxicity of NK cells on killing the WT cell lines. The FACS and WB results showed that the NKG2D and p-PI3K ratio PI3K, MEK1/2, and p-ERK1/2 ratio ERK1/2 were significantly increased in IL-2 and IL15 group compared with uncultured groups. Conclusion. The abnormal NK cell-mediated cytotoxicity may cause the occurrence of WT. Costimulation of WT patients autologous NK cells could effectively enhance the antitumor reaction which involved in activation of NKG2D-mediated MAPK signaling pathway.

Published: September 2022

Agriculture continues to be vital to Africa’s future in both spatial and temporal contexts. Nonetheless, the sector keeps on confronting production challenges as a result of frequent and extended droughts, and these necessitate the use of drought-resistant crops such as sorghum. This review initiates one of the most common food grains grown in the poorest countries and the most food-insecure regions of the nation. We used deductive logical reasoning to develop a comprehensive scientific understanding of the crop that can be used to inform future research and policies. Various exclusion and inclusion criteria were used to filter the most prominent findings. Sorghum has the highest utility for its climatic adaptability and has grown for multiple purposes: From staple to industrial outcomes, its economic, social value, and health outcomes, and for animal silage. It is a gluten-free crop, has high nutritive value, and is preferred by healthy consumers. It is among the top five cereal crops worldwide in both production and acreage. This has necessitated the development of coping measures, such as the cultivation of drought-tolerant crops suitable for the affected areas. Therefore, this crop is used to ensure productivity, food security, and availability of food when other crops fail and food deficit and famine are affected in the region. This will contribute to the ongoing discussion on how to better inform private and public sector policy and investments in Ethiopia to increase sorghum and other drought-tolerant crop production, transform agriculture, improve nutrition, and food systems, and end hunger, food insecurity, and poverty.
Application of the Lagrange Equation for Intelligent Sensor Vibration Control for Power Network Monitoring
Authors: Cheng Xiaojing
Published: September 2022

Objective. In order to control the vibration of the beam structure more effectively and improve the safety and availability of the beam structure, an application study of the Lagrange equation for vibration control of smart sensors for power grid monitoring is proposed. The vibration of the beam structure, the displacement of the beam structure under the excitation of seismic acceleration, the response analytical electrical formula, and the displacement response formula of the beam structure under the action of the kinematic force are deduced. The optimal parameters of the beam-TMDI system are given, and the parameter sensitivity analysis is carried out. Then, the control effect of the TMDI system is studied by numerical analysis, and the vibration reduction effect of the TMDI system and the tuned mass damper (TMD) system is compared. Experimental results show that when the mass ratio

μ

of the TMDI system and the TMD system are both set to a fixed value of 0.005, and the parameter

β

of the TMDI system is set to 0, namely

β
=
b
=
0

, at this time, the TMDI system degenerates into a TMD system. The TMD natural frequency is 14.179 rad/s and the damping ratio is 0.0432 by the DH optimization method, while the TMD natural frequency is 14.1812 rad/s, and the damping ratio is 0.0436 by the augmented Lagrangian optimization algorithm. Conclusion. The vibration displacement response spectrum of a beam structure obtained by the frequency domain method can effectively reflect electricity in the displacement response of a beam structure. The parameters that minimize the vibration response of the beam structure can be accurately obtained by using the augmented Lagrangian parameter optimization method. The sensitivity of the TMDI system is controlled by the inertial device, and the inertial device has a significant impact on its robustness. The vibration reduction performance of the TMDI system is obviously better than in the conventional TMD systems.

Published: September 2022

Whiteflies are one of the most devastating horticultural pests attacking tomatoes. Although there are several control methods for the control of whitefly pests, the integrated application of entomopathogenic fungi (IPM) with chemical and botanical insecticides has proven more effective than individual control agents. This study was carried out to evaluate individual and combined treatments of entomopathogens B. bassiana, M. anisopliae, B. thuringiensis, Hunter 40 EC, and neem oil for the control of whitefly species on tomato (Solanum lycopersicum) under greenhouse and field condition. The greenhouse study showed that the different treatments resulted in a 58.48 to 100% reduction of nymphs and a 52.06 to 100% reduction of adults on both Galilea and Melkashola tomato varieties under greenhouse conditions. The combined treatments of AAUMB-29 + Neem oil displayed a higher yield (423.3 g fruits/plant) on the Gelilea tomato variety, and AAUDM-43 + Hunter 40 EC displayed a yield of (376.66 g/plant) on the Melkashola tomato variety. Under field conditions, the application of AAUMB-29 + Hunter 40 EC + Neem oil significantly decreased the whitefly population by 91.93% (P<0.001) after 10 days of the fourth spray. The result of fruit yield of tomato was significantly higher in all treatments (31.17 t to 70.42 t·ha−1) compared to untreated control (25.83 t·ha−1). Among the treatments, AAUMB-29 + Hunter 40 EC + Neem oil gave the highest fruit yield of 70.42 t·ha−1 followed by AAUMB-29 + Hunter 40 EC (64.50 t·ha−1) on the Galilea tomato variety under field conditions. The combined treatment of AAUMB-29 + Hunter 40 EC + Neem oil was the most effective with lower whitefly infestation, higher marketable yields, and less percentage of yield losses. Further investigations are required to determine the optimization and practicability of this integrated application of treatments for the control of both sucking and chewing insect pests under field conditions.

It is usual practice to optimize the various processing parameters in order to achieve well-organized and lucrative process conditions. For the creation of tungsten carbide/silicon nitride/AA2219 composites, sintering temperature, sintering pressure, dwelling time, and heating rate all must be optimized. Design of experiments and analysis of variance were employed to assess the factors’ contributions to density as well as microhardness response variables. It was decided to test the admixed powders and Vickers hardness tester, optical microscope, and Archimedes-based density testing to evaluate the sintered compacts. The optimum spark plasma sintering factors were a temperature of 500°C, a pressure of 30 MPa, a dwelling time of 8 minutes, and a heat rate of 160 °C/min, resulting in an extreme density of 2.71 g/cm3 and a maximum microhardness of 38.61 HV (0.38 GPa).

) groups and treated with laparoscopic surgery and laparotomy, respectively. As well as postoperative complications and survival rates, the levels of inflammatory substances, stress response, immunological function, and perioperative markers were compared between the two groups. There was no significant difference in the postoperative exhaust time between the two groups (

P
>
0.05

). Compared with the control group, the observation group showed longer operation time, faster recovery of intestinal function, shorter hospital stay, and less intraoperative bleeding amount (

P

). The serum contents of hs-CRP, TNF-α, IL-6, norepinephrine, adrenaline, and cortisol at 1 d, 3 d, and 5 d after surgery were significantly higher than before in both groups (

P
<
0.05

). Moreover, the serum contents of hs-CRP, TNF-α, IL-6, norepinephrine, adrenaline, and cortisol in the observation group were significantly lower than that in the control group (

P
<
0.05

). At 10 days following surgery, immune index levels had dramatically increased in both groups, with noticeably higher immune index levels in the observation group than in the control group (

P
<
0.05

). There were no appreciable differences in the two groups’ 2-year survival rates (

P
>
0.05

), but the complication rate was much greater in the control group (

P
<
0.05

). To sum up, after laparoscopic surgery, patients had fewer complications, shorter hospital stay, lower inflammatory factor expression, less stress response, better immune function, less trauma, faster recovery, and improved quality of life.
Assessment of Production and Utilization Practices of Orange-Fleshed Sweet Potatoes (Ipomoea Batatas L.) in Sidama Region, Ethiopia
Authors: Hendebo Miheret , Ibrahim Ali Mohammed , Gurmu Fekadu , Beshir Hussien Mohammed
Published: September 2022

Sweet potato (Ipomoea batatas L.) is an important crop which ensures food security in developing countries. It can be harvested at any stage as needed, thereby providing a flexible source of food and income for rural families that are most vulnerable to crop failures and cash income fluctuations. The production and consumption of orange-fleshed sweet potatoes (OFSP) by smallholder farmers in the Sidama region of Southern Ethiopia were explored in this study to identify key problems and opportunities in OFSP production. A preliminary investigation and rudimentary data collection were used to gather data. The data were analyzed using descriptive statistics, multiple linear regression, and index grading. Based on the descriptive analysis, smallholder farmers have small landholdings of 0.51 ha per family. Farmers conserve their planting materials by leaving them in the field. This causes the materials to be extensively infested with diseases, insects, and other vertebrate pests. Farmers (54.4%) do not apply inorganic fertilizersassuming that it stimulates more vegetative growth and results in tasteless storage roots. The continuous cultivation of OFSP without fertilizer application results in nutrient depletion and reduced yield. Further, the production and utilization of OFSP in the Sidama region is constrained by factors such as diseases, lack of storage facilities, lack of planting materials, drought, insect pests, low market price, and shortage of money to purchase inputs. According to the index ranking, drought, shortage of planting material, diseases, and insect pests were the most important. Combinations of social, ecological, and economic factors limit the production of sweet potatoes and therefore, a stronger extension system on agronomic practices and credit system should be made accessible to the farmers.

Intraprediction Complexity Control Algorithm Based on Visual Saliency
Authors: Shan Nana , Zhou Wei , Duan Zhemin
Published: September 2022

Intraprediction is one of the most complex parts of High-Efficiency Video Coding (HEVC), because it selects the best prediction mode by calculating the cost of every Coding Unit (CU), which provides higher complexity of intracoding. Visual saliency map can show the attention regions of the human eyes, which is generated by certain static and space-time saliency detection method. By analyzing the percentage of coding time for different size CU, and the relation of visual saliency and CU depth, an intraprediction complexity control algorithm based on visual saliency is proposed in this paper. Based on the feature of the video and the target level, the saliency threshold is adapted to determine whether the current CU in the intraprediction processing should be split into smaller CUs or the division processing should be stopped early. Three samples were compared by the proposed algorithm and other algorithm, and the proposed algorithm has better performance in PSNR, BitRate, and coding time. Experimental results show that this algorithm can effectively control the coding complexity of intraprediction with minimal visual loss and can be applied to a number of scenarios, such as real-time video coding.

Authors: Beshr Ashraf A. A. , Israil Magdy , Abden Hameda A. , Farhan Magda H.
Published: September 2022

Coronavirus disease (COVID‐19) is a viral infection caused by the SARS‐CoV‐2 virus that first surfaced in December 2019. According to the World Health Organization, most persons infected with this virus suffer from mild to severe respiratory infections and recover without specific treatment or hospitalization. Some people, however, may acquire serious illnesses that need medical attention and isolation facilities. This paper investigates the use of multi‐criteria decision analysis (MCDA) based on GIS technology to determine the optimal site selection for isolation hospitals for coronavirus patients in Nile Delta region in Egypt using the fuzzy analytical hierarchy process (F‐AHP) and the weighted overlay tool analysis method (WOA). The research of isolation hospital site selection in Nile Delta governorates in Egypt is one of the areas that have received insufficient attention due to the current global coronavirus epidemic. Several criteria are applied to identify and select the isolation hospital location, including World Health Organization regulations, Egyptian Ministry of Health conditions, previous research studies, and field visits. Geodatabase is created using ArcGIS Pro software, and manual digitization is done. As a conclusion of the study, numerous additional optimal sites for isolated hospitals have been found and chosen. There are around 29 proposed ideal sites for isolated hospitals utilizing F‐AHP and approximately 24 sites using WOA approach in Nile Delta region. These planned hospital locations might be permanent as a central hospital or temporary, to be relocated after the epidemic is over. The paper emphasizes the need to use the study criteria while selecting and defining the location of coronavirus isolation hospitals.

[Retracted] Static and Dynamic Demonstration of the Ecological Level of Ethnic Cultural Industries Based on the Internet of Things and Environmental Responsibility
Authors: Xie Weiguang , Yu Shanbo
Published: September 2022

The cultural industry of ethnic minorities carries the wisdom of many ancients. In today’s modernization, ethnic minority cultural industry products can still impress people’s hearts with exquisite handicrafts, natural materials, and strong culture. The rise in demand for ethnic cultural products will bring about an increase in the demand for raw materials for handmade products, which is bound to have an impact on the environment. This paper is aimed at modeling and analyzing the ecological level of minority cultural industries based on the background of the Internet of Things (IoT) and environmental responsibility. In the experiment, this paper analyzed the ecological level of the traditional fish skin industry by taking the Hezhe people in Heilongjiang as an example. Aiming at the cultural industry of the Hezhe people, this paper selected the fish skin industry as the object of empirical analysis from the fish culture it represents. According to the ecological level of the industry, this paper selected the three first‐level indicators of production energy saving level, ecological environmental protection level, and production emission reduction level and its 12 subordinate second‐level indicators to model and analyze the fish skin industry of the Hezhe people. The analysis results showed that the industrial ecological level of the Hezhe fish skin industry in the past 16 years reached the standard rate of more than 75%. However, the ecological level index for the three years of 2018, 2019, and 2020 was between 0.3 and 0.5, which indicated that the ecological level in these three years was very low. This was caused by the mechanization of the handicraft industry in recent years.

Published: September 2022

Objective: The study aimed to investigate the value of pulmonary function test (PFT) in evaluating and predicting pulmonary arterial hypertension (PAH) in patients with connective tissue disease (CTD). Methods: This was a prospective observational study recruiting patients diagnosed with CTD-PAH. Patients with interstitial lung disease and pulmonary hypertension induced by other causes were not eligible for enrollment. All patients were assessed for PAH every 1–3 months. A patient was considered to have clinical improvement if the grade of risk stratification declined or at least two parameters improved during follow-up, otherwise no improvement. Results: A total of 31 patients with CTD-PAH were recruited in this study. Nearly 70% of patients had declined forced vital capacity (FVC), 60% had declined total lung capacity and maximum expiratory flow at 50% of vital capacity, and 95% had normal or mild decline in forced expiratory volume in 1 second (FEV1)/FVC. A decline in diffusing capacity of the lung for carbon monoxide (DLCO) was present in 96% of patients, and 60% were moderate to severe. Furthermore, 50% of patients had an FVC/DLCO ratio of less than 1.4. Univariate analysis showed that FEV1/FVC, DLCO, and FVC/DLCO were associated with disease prognosis. After adjusting for age as a confounding factor, multivariate logistic regression analysis revealed that DLCO was an independent predictive factor for the prognosis of CTD-PAH. Conclusion: The pulmonary function of patients with CTD-PAH is abnormal in parameters such as lung volume, small airway, and gas exchange. PFT can reveal complex pathophysiological changes in the lungs of CTD-PAH patients and predict prognosis.

Authors: Fang Dejian
Published: September 2022

In order to improve the efficiency and throughput of data transmission of laboratory instruments and equipment and reduce resource consumption, an optimization algorithm of data transmission efficiency of laboratory instruments and equipment based on frequency control is proposed. Firstly, the frequency control method is used to construct the real-time data transmission model of laboratory instruments and equipment, and the optimal equivalent load of instruments and equipment is obtained. Secondly, the filtering time constant is selected through the first-order low-pass filtering control model to obtain the value range of the filtering time constant. Finally, the filter time constant is optimized in real time according to the stabilized power prediction value sequence, the optimization objective function of data transmission efficiency is obtained, and the optimization of data transmission efficiency is realized by solving the objective function. The experimental results show that compared with the traditional algorithm, this algorithm can improve the data transmission efficiency of laboratory instruments and equipment and improve the data throughput and reduce the resource consumption. The data transmission efficiency of this algorithm is always maintained at more than 85%.

Objective. This research is aimed at investigating the relationship between liver fibrosis in viral hepatitis and macrophage colony-stimulating factor (M-CSF), tissue inhibitor of matrix metalloproteinase (TIMP-1), and ceruloplasmin (CER) in serum level. Methods. Patients were randomly selected among those admitted to our hospital, and 60 healthy volunteers were chosen to serve as control participants. The levels of serum M-CSF, CER, and TIMP-1 were compared. According to the severity of their liver fibrosis, patients with CHB were separated into four groups: S1, S2, S3, and S4. Serum levels of M-CSF, CER, and TIMP-1 were correlated with liver fibrosis and hepatitis markers, and the diagnostic usefulness of the three indices was assessed with liver cirrhosis patients. Results. Increases in M-CSF and TIMP-1 in the CHB group but decreases in CER were statistically significant (

P
<
0.05

). Serum levels of M-CSF, CER, TIMP-1, HA, PC-III, C-IV, and LN differed significantly across the four study groups (

P
<
0.05

). Over time, as liver fibrosis worsened, we observed a progressive uptick in M-CSF, TIMP-1, LN, HA, C-IV, and PC-III levels and a progressive downtick in CER levels, with significant (

P
<
0.05

) differences between the groups. There was a significant positive correlation between liver fibrosis and serum M-CSF, PC-III, TIMP-1, HA, LN, and C-IV levels in the CHB group (

P
<
0.05

) and a significant negative correlation between serum CER and these same factors (

P
<
0.05

). The AUC of 0.956 for diagnosing the S4 stage was greater than that of 0.857, 0.851, and 0.817 for M-CSF, CER, and TIMP-1, respectively. Conclusions. In CHB patients, the liver fibrosis degree is associated with the M-CSF, CER, and TIMP-1 levels, and the combined clinical detection of these three markers has better diagnostic significance.

Authors: Pita M. , Lebea L.
Published: September 2022

Copper is one of the first metals to ever be mined and used by humans, and since the dawn of civilization, it has made important contributions to behavioral science. The exploration of copper has provided knowledge of nonfuel minerals and has consequently improved society. The objective of this paper is to investigate the effect of annealing on the microstructure, mechanical properties, and corrosion of copper material before undergoing an accumulative roll bonding process (ARB). The material was heated to 600°C and cooled with water before being rolled by a two-roller rolling machine. The second ARB experiment was conducted on copper material without annealing. The samples were characterized by a light microscope (LM). The ASTM E384 test method was followed during the hardness test. The results show that annealing and applying two passes of the ARB process reduce the grain size by 37%, which is significant. It also increases copper hardness by 65% and increases its electrical conductivity by 2.6%. Additionally, the results show that the open circuit potential during the first pass heated sample was −0.07237 V; this increased by 22.16% with the second pass heated sample.

Authors: Wu Yanmin , Qi Jinli
Published: September 2022

The rapid development of the information age brings convenience to human life, but it also brings great challenges to information processing technology. Multimedia enhancement technology is an organic combination of multimedia technology and information processing technology, and it is also an important way of modern multimedia image information processing. However, its usefulness and effectiveness are increasingly negatively affected by the open information environment. The processing effect is also unable to meet the development requirements of the visual field. In order to improve this problem, this paper studied the image transmission and processing system of network-controlled robot on the basis of analyzing the characteristics of the problems existing in the current stage of multimedia technology. On this basis, a new image processing variational model was established and applied to multimedia enhancement technology, which improved the efficiency and effect of image information processing. Finally, the feasibility of its application function and performance was tested by experiments. The test results showed that in the difficult mode of the image processing task, the refresh time of the model in this paper in the multimedia enhancement technology was 1.13 s in total, which was not much different from the test results in the easy mode. Also, in the load stress test, the comprehensive test values under full-function operation and partial-function operation were 42.04% and 20.92%, respectively. Compared with the traditional model, the model in this paper has stronger carrying capacity in multimedia enhancement technology and has better processing ability and stability.
