Published: July 2022

Background and Aim. Biodentine refers to a bioactive material commonly applied for dental restoration in clinical practice, but poor adhesion of the Biodentine to the restorative materials could affect the quality and long-term integrity of the final restoration. The study aimed to assess shear bond strength (SBS) of two resin-based composites to Biodentine using three commercially available 7th generation bonding agents. Methods. Forty-eight acrylic blocks having central holes with a nominal diameter of 4 mm and a depth of 2 mm were prepared. The holes of the acrylic blocks were filled with Biodentine, which was prepared following the guidelines provided by the manufacturer. Then, the specimens were divided into six groups (n = 8). Groups 1, 2, and 3, Tetric N-Ceram composite bonded to Biodentine with Tetric N-bond, Xeno V+, Bond Force bond, respectively. Group 4, 5, and 6, Filtek Z350 bonded to Biodentine with the same three adhesives. The specimens were placed in distilled water for 24 hours and tested for the SBS in a universal testing machine at a crosshead speed of 1 mm/min. The test data were listed in a table and independent samples t-test and analysis of variance (ANOVA) were conducted as a part of the statistical analysis. Results. The Tetric N bonding agent achieved the highest SBS followed by Bond Force, and Xeno V and highly significant difference was found. On the other hand, an overall increase in the SBS values of the Tetric N-Ceram resin was noticed in comparison with the Filtek Z350 and the differences was statistically significant. Although the specimens failed in adhesive, cohesive and mixed fracture modes but the cohesive was found to be the dominant failure mode in all groups. Conclusion. Among the tested bonding agents and resin composites, the Tetric N-Ceram composite bonded by Tetric N-bond self-etch adhesive with the Biodentine showed the highest SBS compared to the other combinations.

Authors: Yi Liang , Xie Yuan , Lin Chang
Published: July 2022

Buildings and the construction sector account substantially for global energy consumption. In hot-humid areas of China, suboptimal thermal comfort in classrooms has heightened their cooling load and energy consumption. It is necessary to renovate the buildings of outdated code according to the current weather conditions to save energy. This study thus aimed to examine the thermal effects of such designs on the cooling load, based on an actual classroom building during summers in hot-humid southern China. Using air temperature and PMV values to evaluate thermal comfort, this study conducted simulation through EnergyPlus and DesignBuilder. The resultant updated typical meteorological year (TMY) and the monthly and hourly analyses of indoor thermal comfort revealed persistent classroom overheating. To mitigate the cooling load, numerous design variables were investigated: space form, roofing, external walls, windows, and shading devices. Evaluative comparisons found that appropriate choice of external windows and shading devices represented the two most effective strategies in mitigating the cooling load. Furthermore, jointly applying effective retrofit strategies to the building yielded a favorable reduction in the annual cooling energy consumption by 16.6%. The findings herein are envisioned to provide evidence-based referential guidance for building designs for classrooms in a hot-humid climate.

Authors: Jia Zhongyuan
Published: July 2022

To overcome the limitations of the traditional teaching system and improve learners’ language learning efficiency by incorporating personalized allocation of learning resources and learning evaluation into the Chinese as a foreign language teaching system (CFLTS). This paper aims to deeply study the overall design of the intelligent teaching system (ITS) for CFLTS. Firstly, this paper develops an ITS for CFLTS. It focuses on the intelligence teaching system’s structural planning and structural design. The system functional structure and the specific characteristics and recommendations module constitute a two-way teaching quality evaluation module. The elite teaching optimization algorithm based on the feedback mechanism is adopted. The students are divided into excellent and poor students after the feedback mechanism is added to split the student stage. Next, they dynamically adjust the scale of excellent and poor students, conduct feedback communication between poor students and teachers, and strengthen the convergence ability. Finally, self-learning for good students is arranged by performing an excellent local search and including the feedback stage to broaden the range of learning methods and improve the ability to find global teaching resources. The completion of all these steps ensures that the design of an ITS for CFLTS is now complete. According to the experimental results, the ITS proposed in this work has a higher level of overall stability, effectively improves students’ learning efficiency and teaching quality, and can better meet the needs of Chinese language learners.

Authors: Gong Jing , Wu Jingjing , Zhang Mingshun , Gan Weihua
Published: July 2022

Objective. Our previous research showed that TCR+CD4-CD8-double-negative (DN) T cells protect renal epithelial cells from cisplatin-induced acute kidney injury (AKI). Therefore, this study is aimed at investigating the mechanism underlying the effect of DN T cells against Cis-induced AKI. Methods. HK-2 cells cultured alone or with DN T cells were treated with or without Cis. After treatment, the cell viability and death were analyzed by a CCK-8 kit and flow cytometric assay with Annexin V/PI staining, respectively. The expressions of inflammatory factors in HK-2 and DN T cells were analyzed using qPCR. The expression levels of nephrotoxicity-associated biomarkers (KIM, calbindin, and TIMP-1), Bcl-2, and angiotensin AT2 receptor (AT2R) were determined by Western blot and qPCR. Results. The administration of cisplatin significantly decreased the cell viability and AT2R expression, and increased cell death, inflammatory factors, and nephrotoxicity-associated biomarkers of HK-2 cells, while these effects were partly attenuated when cocultured with DN T cells. IL-10 expression was significantly increased in DN T cells after coculture, and cisplatin treatment aggravated this elevation. IL-10 supplementation exhibited a similar effect to coculture, whereas anti-IL-10 antibody reversed the effect of coculture on cisplatin-treated HK-2 cells. Finally, PD123319, an AT2R antagonist, also reversed the effect of IL-10 and coculture on the cell viability, death, and the expression of KIM, calbindin, TIMP-1, and Bcl-2 of cisplatin-treated HK-2 cells. Conclusions. DN T cells protected HK-2 cells from cisplatin-induced injury through IL-10/AT2R axis, which may act as a potential target for the treatment of cisplatin-induced AKI.

Published: July 2022

Structures with negative Poisson’s ratios have wide applications in automotive design, owing to their excellent mechanical properties and good energy absorption capability. This type of structure can be used to design lightweight components. We used a double-arrow negative Poisson ratio structure and embedded lock assembly process to design a 3D lattice structure with a negative Poisson ratio. Moreover, we selected different design parameters for a simulation analysis and experimental research. The performances of the lattice structures with different parameters were compared and analyzed under different test conditions, including out-of-plane compression, three-point bending, and low-speed impact. The findings reported here pave the way for the development of new 3D auxetic materials with significantly expanded design space and potential applications by reducing the difficulty of the manufacturing process.
Study on Acoustic Emission and Damage Mechanical Properties of Freeze-Thaw Sandstone under Uniaxial Compression
Authors: Liang Bo , Yang Gengshe , Yu Jinjie
Published: July 2022

The damage strength of freeze-thaw rock provides an important reference for stability evaluations used during rock engineering in cold regions. In this paper, real-time acoustic emission tests of saturated sandstone are performed after various freeze-thaw cycles to study the uniaxial compressive strength and deformation characteristics of the resulting materials. The macro-meso damage evolution law of loaded sandstone is studied under the action of freeze-thaw cycles. The results show the following: (1) The saturated water absorption of sandstone increases, the peak strength and elastic modulus loss rates of sandstone increase linearly, and the frost resistance of the rock decreases with the number of freeze-thaw cycles. The sandstone failure mode gradually shifts from splitting failure to complex splitting shear failure of the failure surface. (2) If fewer than 10 freeze-thaw cycles are applied, the ring count signals at the compaction stage and after the peak strength is reached are extremely weak under a uniaxial compression load. With additional freeze-thaw cycles, damage inside the rock accumulates gradually, and the ring count signal appears during the rock compaction stage, fluctuates up and down, and continues until the peak strength is reached. When the compressive strength reaches its peak, the ring count intensity signal increases suddenly, and the frequency is high. After the strength reaches its peak, the acoustic emission signal shows that the rock sample still has some residual strength. As the number of freeze-thaw cycles increases, the cumulative ring count of sandstone gradually changes from the jumping stage to gradual growth. The acoustic emission characteristic parameters and ring count reflect damage to and expansion of freeze-thaw sandstone. (3) The cumulative extent of rock damage reaches the threshold value under loading and increases linearly until the rock is destroyed. When more freeze-thaw cycles are used, the time required for the rock to reach this threshold value is shorter, and the time required for sandstone damage is reduced gradually. These results provide a reference for the study of freeze-thaw damage and rock stability in cold regions.
Effect of Sports Energy Drink on Fat Metabolism and Weight Loss of College Students
Authors: Chu Huan , Zhou Wenyong , Wang Shanshan
Published: July 2022

In order to solve the problem of fat metabolism and weight loss of college students, this paper puts forward a problem of the influence of sports energy drinks. Energy drink is a combination of sports drinks, energy drinks, and other special functional drinks (such as nutrient drinks with added vitamins and minerals; herbal drinks with Chinese herbal ingredients), a general term for a large category of drinks that provide specific health and nutritional functions for special groups of people. With the continuous improvement of people's consumption level and their constant attention to their own health, the consumption of energy drinks is also increasing. Energy drinks have become a new generation of drinks after carbonated drinks, drinking water, fruit and vegetable juice, and tea. At present, the total annual output of beverages in the world exceeds 300 billion liters, and functional beverages have become the fastest growing beverage varieties. Fat is the main energy supply material for endurance sports. The catabolism of fat during sports is the key link for the body to obtain energy. For the general population, abnormal fat metabolism is the main cause of obesity. In this paper, 10 healthy male and female college students without training experience were used to determine the maximum fat metabolism intensity FATmax. Based on this, the exercise prescription of maximum fat oxidation intensity for 8 weeks was formulated. The functional ability, maximum oxygen uptake, body fat percentage, quiet heart rate, blood pressure, and vital capacity before and after the experiment were measured to observe the exercise effect. The fitness effect of maximum fat metabolism intensity was studied to provide theoretical support for college students’ fitness exercise. The study found that there was no significant difference between boys and girls in the maximum fat oxidation rate and FATmax, and girls’ E. C. and running speed corresponding to FATmax were significantly lower than those of boys. After 8 weeks of exercise prescription exercise of maximum fat metabolism intensity, the E. C. and maximum oxygen uptake of boys and girls increased significantly; quiet heart rate, vital capacity index, and body fat percentage were significantly improved; and the changes in girls were more significant than boys. The results show that there is no gender difference in FATmax. The corresponding exercise intensity (7.22 METs for boys and 5.25 METs for girls) and running speed (9.73 km/h for boys and 8.65 km/h for girls) can be used as a reference for formulating college students’ fitness exercise prescriptions. The fitness exercise prescription based on FATmax can improve cardiopulmonary function and body composition, especially for girls. FATmax can be used as a reference standard for formulating fitness exercise prescriptions.

Published: July 2022

Background. Facial fractures can be accompanied by serious and life-threatening injuries such as cervical spine injury (CSI), which can lead to serious consequences if misdiagnosed. Objective. To assess the patterns of maxillofacial fractures and to explore the association between these fractures and cervical spine injuries (CSIs) in patients with a traumatic facial injury. Methods. A retrospective analysis was conducted on the data of the subjects who were admitted to the King Abdullah University Hospital (KAUH) and had a maxillofacial fracture in the period from January 2017 through December 2020. Stepwise binary logistic regression analysis was conducted to find the variables which are significantly and independently associated with CSIs. Results. A total of 394 maxillofacial fractures were reported for a total of 221 subjects. The mandible was the most common site of the reported fractures (41.88%). The majority of the subjects had associated injuries (70.6%), of which 82.7% were CSIs. The most common type of the CSIs was the vertebral fracture (52%). Increased age (OR = 1.543,

P

), having a mandibular fracture (OR = 4.382,

P
<
0.01

), and having a maxillary fracture (OR = 3.269,

P
<
0.05

) were significantly associated with the presence of CSI. Conclusion. The current study revealed that the most common type of facial fracture occurred in the mandible area, and CSI was the most common fracture-associated injury (82.7%). Increased age and having mandibular or maxillary fracture were associated with an increased risk of developing CSI. Therefore, it is necessary to rule out the presence of concomitant CSI during the emergency management of maxillofacial fractures, particularly for elderly patients and those with mandibular or maxillary fractures.
Development of Tourism for Culture and Innovation Based on Convergence of Data in the Perspective of Industrial Integration
Authors: Yang Ranran
Published: July 2022

The blurring of industry lines, or the phenomenon of new products or industries crossing over, is becoming more common. Academic circles have taken notice of this phenomenon, and the term “industrial integration” has been coined to describe the shift in interindustry relations. It can not only meet the demand of urban residents to return to nature and tradition with the connotation of rural ecology, agricultural production, and farmer’s life in tourism for culture and innovation, as well as the expression of tourism activities. However, traditional tourism, which is primarily based on sightseeing, is no longer able to meet the demands of customers. People are increasingly interested in interactive, creative, experiential, and diverse tourism, and tourism destinations and services are increasingly valued for their cultural connotation and unique creativity. The basic idea behind data convergence as a data processing method is to make extensive use of data from all aspects of the system in order to extract the most effective information about the object or environment, resulting in a more precise and comprehensive understanding of the observed object or environment. As a result, this paper uses convergence of the data method based on a large amount of empirical research experience to study the driving factors, paths, and patterns of the fusion of commercial and innovative businesses with the tourism industry. It is based on industrial fusion theory and value chain theory and uses convergence of the data method based on a large amount of empirical research experience to study the driving factors, paths, and patterns of the fusion of commercial and innovative businesses with the tourism industry. The experimental results show that the global adjustment algorithm improves the model (i.e., the evidence) without changing the fusion formula. The fusion results improved by 0.595 on average when compared to the D-S algorithm, and the probability rapidly increased. As a result, the study of tourism for cultural and innovation development based on data convergence summarises the interaction between subsystems with logical thinking and depicts the process and direction of tourism creative industry fusion development in a more image and concrete manner.

Authors: Sui Weixin , Zhou Yimin , Zhu Sizheng , Xu Ye , Wang Shanshan , Wang Dan
Published: July 2022

The fast popularization of the Internet of Things (IoT) has caused the data scale to increase geometrically. The data of IoT devices is processed on the cloud, but the way of processing data in the cloud center gradually causes problems, such as communication delay, latency, and privacy leakage. Edge computing sinks some cloud center services to the edge of the device so that data processing is completed in the terminal network, thereby realizing rapid data processing. At the same time, since long-distance communication is avoided, user data is processed locally, so that user privacy data can be safely protected. A genetic algorithm is a type of heuristic algorithm that is based on the genetic development of organisms in nature and has a high global optimization capability. The basic aim and objective of this paper is to study the existing edge computing framework along with computing offloading technology. The genetic algorithm is investigated using multiedge computing-oriented collaborative computing offloading, which is helpful to the IoT’s growth as well as the generation and the use of data. The use of a genetic algorithm based on a color graph for load balancing on several edge servers is also investigated. In terms of the study’s performance evaluation, it is obvious that our proposed approach produces superior results than previous studies.

Authors: Jiang Zhen
Published: July 2022

As the core component of a physical education teacher’s professional skills, sports skills are the precondition for physical education teachers to teach and also a key factor for the level of a physical education teacher’s professional skills. According to the survey, the current sports skills of graduates majoring in physical education are not satisfactory, and a considerable number of students think that their sports skills are difficult to meet the needs of educational practice. In the era of basic education reform and teacher professional development, we analyze the advantages and make up for the deficiencies in order to improve the effect of physical education professional sports skills training and meet the society’s needs for high‐skilled sports talents. The experiment randomly selected five physical education students from five schools and five students as the research objects. Based on the support vector machine, the questionnaire survey method, interview method, and statistical method are used to conduct related research and analysis on it. The results show that sports skills are the advanced stage of sports technology development. At present, there are many sports skills that students learn in major colleges and universities, but they really master the sports skills. Motor skills are rare. At present, the future talents of physical education major are mostly “compound” and “specialized” talents, and there are few references to applied talents. The training objectives should be clear, the curriculum should be closely linked to the training objectives, the selection of skills teaching methods by teachers should be adapted to the teaching content, and teachers and students should be actively active among these elements, which are both used and influenced by these elements.
Tube-MPC Control via Notch Filter for Flexible Air-Breathing Hypersonic Vehicle with Actuator Fault
Authors: Yang Xiaohe , Lv Weijie , Mi Hanpeng , Hu Chaofang , Hu Yongtai
Published: July 2022

In this paper, the tube model predictive control (Tube-MPC) via notch filter is proposed for flexible air-breathing hypersonic vehicle with actuator fault. Firstly, considering the low-order flexible modes, the polytopic linear parameter varying (LPV) model of flexible air-breathing hypersonic vehicle is established using Jacobian linearization and tensor product. Actuator fault and parameter uncertainty are transformed into a lumped disturbance term. The baseline Tube-MPC trajectory tracking controller is developed by designing robust auxiliary feedback control law and nominal control law. In order to weaken the effect of flexibility, a notch filter is introduced to eliminate the frequency response peak of flexible modes. And the effect of notch filter on control performance and stability is analysed. Secondly, an alternative controller design strategy is proposed to ensure stability of the closed-loop system. The filter and the original nonlinear model are combined together such that the new polytopic LPV model is codesigned. On the basis, the adjustable Tube-MPC controller is developed to improve the control performance and ensure the stability of the system. Finally, the effectiveness of the two controllers is verified by simulations.

How to enhance the effectiveness and recognition of the rule of law education for college students has become an important task of higher education. Therefore, strengthening the legal education of college students is not only an inevitable choice to fully implement the rule of law but also a realistic requirement to improve the level of higher education and realize the all‐round development of college students. College students’ mental health education is an important part of the talent training system of colleges and universities, and in‐depth exploration of the ideological and political laws of college students’ mental health education courses is an inevitable requirement for implementing the fundamental task of Lide Shuren. College students’ mental health education courses must be integrated into the ideological and political concepts of the curriculum, reflect the political orientation of ideological and political work, embody the law of educating people with morality as the first, and embody the practical purpose of psychology to pay attention to personality improvement. It is necessary to optimize the content of education and teaching, excavate the elements of ideological politics in the curriculum, enrich the resources of ideological politics in the curriculum, and explore a new way of reforming the ideological and political education curriculum for college students from the aspects of deeply planting family and national feelings, enhancing political identity, strengthening cultural self‐confidence, cultivating Chinese temperament, clarifying the meaning of life, strengthening mission responsibility, enhancing civic awareness, and developing law‐abiding habits. Strictly regulate the behavior of contemporary college students in the online environment, give full play to the role of legal education, and reduce the incidence of online incidents such as online fraud and cyber violence. This paper puts forward some problems in the current legal education of college students in China and points out the root causes of these problems. Methods for structural reform and advanced cultural construction based on social development are proposed. From a strategic point of view, it is believed that only by managing the reform of legal education and cultivating civic awareness can we completely solve various contradictions and problems among college students in the network environment and pave the way for the development of college students.

In order to improve the transmission effect of low-power communication signal of Internet of Things and compress the enhancement time of low-power communication signal, this paper designs a low-power communication signal enhancement method of Internet of Things based on nonlocal mean denoising. Firstly, the residual of one-dimensional communication layer is preprocessed by convolution core to obtain the residual of one-dimensional communication layer. Then, according to the two classification recognition methods, the noise reduction signal feature recognition of the low-power communication signal of the Internet of Things is realized, the nonlocal mean noise reduction algorithm is used to remove the low-power communication signal of the Internet of Things, and the weight value between similar blocks is calculated according to the European distance method. Finally, the low-power communication signal enhancement of the Internet of Things is realized by the nonlocal mean value denoising method. The experimental results show that the communication signal enhancement time overhead of this method is low, which is always less than 2.6 s. The lowest bit error rate after signal enhancement is about 1%, and the signal-to-noise ratio is up to 18 dB, which shows that this method can achieve signal enhancement.

Objective. This study is aimed at constructing and evaluating a prediction model of severe abdominal pain post-transcatheter arterial chemoembolization in patients with HBV-related primary liver cancer. Methods. Patients with HBV-associated primary liver cancer who received transarterial chemoembolization (TACE) from March 2019 to March 2022 in the Interventional Therapy Department of our hospital were selected as the subjects, and the included 160 patients were randomly divided into modeling group (

n

) and validation group (

n

) in a ratio of 3 : 1. Visual analog scale (VAS) was used to assess pain severity. 120 patients in the modeling group were divided into no/mild abdominal pain group and severe abdominal pain group. The clinical data of the patients, including gender, age, TACE treatment history, vascular invasion, maximum diameter of tumor, infarction degree, preoperative Eastern Oncology Collaboration Group (ECOG) score, and Lipiodol dosage, were analyzed. Receiver operating characteristic (ROC) curve was used to evaluate the predictive value of the prediction model for severe abdominal pain post-TACE. Results. A total of 116 patients (72.50%) had severe abdominal pain after TACE. Univariate analysis showed that severe abdominal pain after TACE in the modeling group was associated with TACE treatment history, maximum tumor diameter, infarction degree, and preoperative ECOG score (all

P
<
0.05

), but not related to gender, age, vascular invasion, and Lipiodol dosage (all

P

0.05

). Logistic regression analysis showed that TACE treatment history, maximum tumor diameter, infarction degree, and preoperative ECOG score were all independent influencing factors for acute abdominal pain post-TACE in HBV-HCC patients (all

P
<
0.05

). The prediction model equation was

, suggesting that the prediction ability of the model was relatively accurate. ROC analysis results showed that the area under the curve (AUC) of severe abdominal pain after TACE was 0.916 (0.862~0.970) and 0.902 (95% CI: 0.841~0.963) in the modeling group and the verification group, respectively. Conclusion. TACE treatment history, tumor maximum diameter, infarction degree, and preoperative ECOG score are independent influencing factors for severe abdominal pain post-TACE in patients with HBV-HCC, and the prediction model established on this basis has good application value.

Objective. Renshen Baidu Powder (RBP) is a famous classic compound of traditional Chinese medicine (TCM) and is commonly used for treating ulcerative colitis (UC). However, the pharmacological mechanism of RBP in treating UC remains unclear. This study investigates the possible mechanism of RBP for UC treatment by network pharmacological analysis and rat validation. Methods. First, the main chemical constituents of RBP were identified using ultrahigh-performance liquid chromatography quadrupole Orbitrap high-resolution mass spectrometry (UHPLC-Q-Orbitrap-HRMS). Then, we obtained targets of identified compounds from the SwissTargetPrediction database and targets associated with UC from GeneCards database. Furthermore, Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) were used to analyze the metabolism-related signaling pathways affected by RBP. Hematoxylin-eosin (HE) staining was used to observe the pathological change of colon in UC rats after treating RBP, and terminal deoxynucleotidyl-transferase (TdT)-mediated dUTP Nick end labeling (TUNEL) staining was used to detect apoptosis after RBP treatment. The enzyme-linked immunosorbent assay (ELISA) was employed to evaluate cytokine levels of TNF-α, IL-1β, and IL-6. The protein expressions of Bax, Bcl-2, PI3K, AKT, and NF-κB in colonic tissue were detected using immunohistochemistry (IHC). Real-time quantitative polymerase chain reaction (RT-QPCR) was employed to evaluate mRNA expression of PI3K, AKT, and NF-κB. Results. We found a total of 24 main compounds and 329 potential targets related to UC. According to KEGG results, 3 main pathways were identified as responsible for UC, including PI3K-AKT, HIF-1, and VEGF signaling pathway. Animal experiments showed that RBP treatment significantly attenuated colon damage in rats with UC. Mechanistically, RBP could inhibit PI3K/AKT/NF-κB pathway; decrease cell apoptosis; and downregulate the expression of TNF-α, IL-1β, and IL-6. Conclusions. This study demonstrated that RBP may exert anti-inflammatory and antiapoptotic therapeutic benefits in UC by regulating the PI3K/AKT/NF-κB signaling pathways, providing a scientific basis for understanding the mechanism of RBP against UC.
