Overseas Communication Strategy and Development Direction of Chinese Film and Television Works in the Internet Era
Authors: Li Jinlu , Ma Wangping
Published: December 2023

In this paper, we first improve the influence propagation model by combining sentiment analysis and propose a new algorithm for node activation probability. Sentiment shift is the dynamic change of node attributes during the propagation of movie and television works. The algorithm for node activation probability has been further improved, and a model for influence propagation applicable to dynamic networks has been proposed. Finally, based on the data of the YouTube Internet platform, this paper analyzes the awareness of overseas audiences on Chinese film and television types, popular elements, publicity methods and domestic and foreign box office from 2010 to 2019. The findings indicate that 0.7379, 0.7031, and 0.5596 foreign viewers believe that three Chinese film and television genres, palace fighting, romance, and youth, are the most popular. Although there are still more than 0.42 million overseas viewers who prefer martial arts genres, they are in a downward stage compared to before. In terms of publicity, more than 0.91 percent of them believe that online social networking areas and chat groups for movie and TV enthusiasts are the most effective forms of publicity. Therefore, this study is an important reference for the development of communication strategies.

Authors: Wang Qin
Published: December 2023

This paper firstly analyzes the essential features of virtual reality technology, constructs the framework of the interior design system based on virtual reality technology, and designs the interaction content of the system as well as the interaction process architecture. Secondly, the interior design system is technically analyzed, and the system’s moving trajectory relative to the environment is determined by using specific point calculation and camera position estimation algorithms, and specific target detection algorithms extract specific target HOC features. Finally, the platform is tested for performance, and the data is quantitatively analyzed using relevant data collected from users in the system as a research sample. The results show that 43 users are satisfied with being able to visit freely in a continuous space, 45 users are all very satisfied with switching the elements in the scene, and they think that replacing the items in the scene is conducive to participating in the design of the program and selecting the decorations they are satisfied with. It shows that the interior design system based on VR technology can directly interact with virtual information in real time, which improves the user’s interactive experience and makes the design “human-oriented”, starting from human needs and feelings.

Authors: Chen Chanjuan
Published: December 2023

The way teachers correct errors in English teaching can cause problems such as psychological pressure, and deep learning technology offers the possibility of automatic error correction. In this paper, the final states of left and right texts are computed by constructing two attention mechanisms, target word-independent and related, and the merged obtained vectors are inputted into the RNN model for grammatical error recognition. In collocation error recognition, a Rank-based word candidate set ranking method is added, and error correction for verb usage is semantically encoded using RNN. The study was analyzed and tested in terms of grammar, collocation, and verbs. The ATT-RNN model accuracy is 3.62 percentage points higher than CAMB, and the difference in recall and F
0.5-value is not more than 0.5 percentage points, which indicates that the algorithmic model has some research value.
Vibrational modal-based characterization and pitch measurement of Pipa
Authors: Cao Lijuan
Published: December 2023

Pipa fretting and pitch measurement are crucial aspects of playing. In this paper, Pipa’s string vibration is simplified to bounded string vibration, and a simplified structural model of Pipa is built. Transverse free vibration is used to establish the vibration equations of Pipa strings, and differential analysis is used to analyze the standing waves. Meanwhile, the vibration of the resonance panel of the Pipa was abstracted into a dynamic model, and the modal analysis was performed using coordinate transformation. In the actual test, the sound signal generated by the vibration was also processed with the help of the Fourier transform, and the pitch of the Pipa was measured by analyzing the time and frequency domains. The vibration of the Pipa panel is complex but regular, with the vibration pitch line at 32.5 hz being a central axis and the vibration pitch line at the frequency of 85 hz being on the upper side, while the vibration corresponding to the frequencies of 32.5 hz and 85 hz can be regarded as a synthesis of the vibration corresponding to the frequency of 175.5 hz. Under the viewpoint of vibration modal analysis, the performance effect of the Pipa has a more refined expression.

Authors: Zhang Limin
Published: December 2023

Aiming at the problems of excessive instantiation complexity, poor interpretability and low generalization ability of knowledge reasoning techniques, this paper unites inductive logic programming ILP with HET neural network to construct a hybrid logic rule and neural network knowledge graph reasoning model - HETIL model. The ILP is utilized to quantify the first-order logic rules, and the multi-layer rule space is constructed by arranging and combining the rules through logic symbols. The rules are instantiated and fed into the HET network, and the attention coefficients aggregate the node features to complete the end-to-end training and generate the rule learning model. Finally, the validity of the model is verified by machine translation experiments, and the results show that the accuracy of the HETIL model in syntactic structure types is more than 0.8 overall. The accuracy in terms of phrase structure reaches 0.879. The average BLEU value of the HETIL model can reach 29.24, which is 1.51 BLEU points higher than the benchmark model. Therefore, the effect of English translation by applying a knowledge graph is better than traditional machine translation.

Authors: Wei Mengfei
Published: December 2023

In this paper, we first construct the discourse knowledge structure of education in different disciplines so that the knowledge points in a certain cross-cutting area between different disciplines are finite sets called knowledge domains, and we use the network of the discourse field system to characterize the logical relations in the knowledge space. Secondly, by defining the elements of hypertext as a triadic structure, a specific chain of dependencies is constructed by combining the hypertext structure with the knowledge space. Finally, we conducted a comparative analysis of the knowledge structure of educational discourse in various disciplines. The results show that among 45 knowledge states, 15 attributes corresponding to the whole column have all 0 information values and the knowledge structure model based on the knowledge space can master the corresponding effective skills of students in different disciplines, which indicates that it realizes this learning process of knowledge learning from point to point, from concrete to abstract, and from part to the whole under different disciplines. This paper examines the use of discourse in various knowledge structures, which may provide insights into the teaching of English academic writing in China.

Authors: Gu Yunhai , Xia Fei , Wang Weihua , Yang Song , Ye Yuqiong
Published: December 2023

RFID technology application has made multi label collisions and security privacy issues increasingly prominent in logistics warehousing. A solution that combines RFID and chaotic encryption algorithm has been proposed and applied to anti-collision and security protocols for logistics warehousing labels to address these issues. Firstly, optimization analysis was conducted on the anti-collision of warehouse system labels using chaotic sequences. By comparing different types of labels, it was determined that the 6TypeB label has good anti-collision ability. On this basis, a bidirectional security authentication protocol based on a chaotic encryption algorithm for 6TypeB labels was studied. The data privacy and security of tags can be effectively protected by this protocol. Finally, a detailed analysis was conducted on the performance of 6TypeB logistics warehousing labels used. The 6TypeB system has an average label recognition rate of 73%, an average transmission efficiency of 95.31%, and an average memory usage rate of 93%. Meanwhile, the average stability of the bidirectional security authentication protocol based on the 6TypeB label system is 92.08%. By utilizing 6TypeB, data privacy and security of RFID can be significantly improved, leading to a new application direction for anti-collision and security of logistics warehousing labels.

Authors: Pandey Anupam , Mondal Arun , Guha Subhanil , Singh Durgesh , Rashmi  , Kundu Sananda
Published: December 2023

In modern days, a sustainable urban planning system requires a balance of vegetation, water, and settlement. The proportions of these surface features directly influence the land surface temperature (LST) in an urban area. LST primarily depends on the emittance of land use/land cover (LULC) categories. In an urban area, changes in LULC categories as well as local warming are the prime regulators of LST change. The study analyses the LULC change and its impact on LST in Imphal City, India. Landsat satellite data for the summer season and winter seasons for 1991, 2001, 2011, and 2021 have been used in this study. Results show that the mean LST of the study area increased at >1% rate/decade. The green area and water area decreased the LST values whereas the built-up area and fallow lands increased the LST values. The study indicates the consequences of proper land conversion to regulate the LST change. Moreover, the influence of population on LST is also determined. The continuous rising trend of population is a positive factor of increasing LST. The study may help the town and country planners to generate sustainable urban land.
Den friska boken och den sjuka läsaren
Authors: Persson Magnus
Published: December 2023

Central agents of the institution of literature (critics, authors, scholars) find it increasingly hard to explain why reading literature is important. This leaves the field open for other interests to legitimize what was once a core value in education and the wider public sphere. One example of this is the increased interest in the potential health effects of producing and consuming culture, including the reading and writing of literature. This article targets the phenomenon of bibliotherapy, i.e. a field and practice concerned with how literature can function as a kind of medicine, thus making the reader healthier, more harmonious etc. Three examples are scrutinized: a popular introduction to bibliotherapy from the early 60s, an anthology from 2004 with a wide range of contributors, from researchers to psychiatrists, and, finally, a “therapeutic diary” from 2010 by the famous Swedish pop singer Caroline af Ugglas and the poet and psychoanalyst Ulf Karl Olov Nilsson. What conceptions of literature and reading can be discerned in these texts? Which values and ideologies lie beneath the renewed interest in literature as a kind of medicine?
Lyssnandets århundrade?
Authors: Adelmann Kent
Published: December 2023

The purpose of this study is to contribute to the knowledge about the importance of listening in modern sound technology and the importance of tradition in reception analysis of literary conversations. The object of inquiry is The poetics of the talking book, a dissertation about how different groups of listeners understand the reception of audio books in literary conversations. The problem explored is: What is the significance of listening in this dissertation? This text analysis has two points of departure. The first point of departure concerns the language used in the dissertation. Results from the study show that the language used is mainly influenced by literary reception and reader response theory, and is therefore misleading to the reader when it comes to listening reception of the talking book. The second point of departure concerns the analytical conceptions used in the dissertation. Results from the study show that the conceptions used comes solely from literary reception and reader response theory, which means that the authors twelve references from listening reception and listening theory are never used in the analysis. The conclusion is that the dissertation seems to be a contradictory representation of a modern expression of audio books, listening research and sound technology and, at the same time, a traditional expression of the western tradition, dominating discourse and literature reception.

Authors: Palo Annbritt , Manderstedt Lena
Published: December 2023

The Swedish school is facing a number of structural and didactic changes. New syllabi have been adopted for the compulsory and the upper secondary school, as well as a new grading system. The aim of this article is threefold. Firstly, we aim to present previous research concerning the teaching of language and writing. Secondly, we aim to analyse the new syllabi in Swedish. Finally, we aim to problematize and discuss these syllabi in the light of previous research. The new syllabi show a progression in the teaching of language and writing, where the indicated text production among the youngest pupils is related to the everyday domain, and the indicated text production for older pupils gradually change into the specialized and the critical/reflexive domains. The article discusses the slight asymmetry between the general objectives for Swedish as a school subject, the central content as it is presented in the syllabi and the assessment criteria in the syllabi for the upper secondary school.
retoriska arbetsprocessens betydelse för möjligheten att framstå med starkt och trovärdigt ethos i muntlig framställning
Authors: Olsson Jers Cecilia
Published: December 2023

Ethos is the part of a person’s identity he or she needs to be able to speak and write with credibility in different communicative situations. Ethos emerges through language, body, thought and action. In each context, we establish our ethos, at the same time as ethos paradoxically is a consequence of context. Ethos is closely related to the language and the expressions we use, and can use, in various types of communication situations. The adolescents in this article report that they experience an imbalance between the teaching of writing and oral communication, although the rhetorical process is the same for written and oral compositions. However, the longitudinal analysis of the teaching process shows that the imbalance students experience is explained by the fact that the rhetorical process (intellectio, inventio, dispositio, elocutio, memoria and actio / pronuntiatio) is treated differently in written and oral composition. Students are offered few opportunities to work on their preparations oral presentation since the emphasis is rather on the practical performance - actio / pronuntiatio. This gives students more opportunities to establish ethos in front of each other than to build ethos together with others.

Authors: Van Zande Jaro , Van Heede Klaas Den , Van Molhem Yves , Van Slycke Sam
Published: December 2023

Background:

Alternative and less invasive methods for laparoscopic sleeve gastrectomy include endoscopic sleeve gastroplasty (ESG), where the stomach is transformed into a narrow tube by using an endoscopic suturing device. Despite satisfying weight loss results, severe adverse events, including gastric perforation, have occurred.

Case Presentation:

This case report describes a 38-year-old woman with acute abdominal pain 4 days after ESG. An emergency laparoscopic exploration revealed a stomach perforation fixed to the anterior abdominal wall by a suture anchor of the gastroplasty.

Conclusion:

A full-thickness perforation harming neighboring organs and structures is a possible complication after ESG. Therefore, this procedure should only be performed if morbidity can be monitored during the procedure to avoid situations where dangerous complications remain unrecognized for too long.

Published: December 2023

Background: Although the last few years showed growth in the role of interventional radiology (IR) in treating various conditions, the specialty faces several difficulties including a shortage of interventional radiologists and inadequate awareness among undergraduate students because of the limited exposure during medical school. Therefore, this study aims to evaluate the level of knowledge and awareness of IR among Clinical Years Medical Students of Umm Al-Qura University.

Methodology: This was a cross-sectional, survey-based study at Umm Al-Qura University, Makkah, Saudi Arabia, which included 358 medical students.

Results: Most of the participants rated their knowledge of IR as either adequate or poor (39.1% each), and 7.3% reported that they knew nothing about IR, while 3.4% responded that they had excellent knowledge of IR. Many of the respondents (58.7%) were not interested in considering a career in IR. Only a few students (10.3%) received elective radiology training. Additionally, 55% thought the correct route for training interventional radiologists was from both surgical and radiological fields, while 36% thought they were only radiologically trained.

Conclusion: This study demonstrated that medical students\' knowledge and awareness of IR are poor. This can be improved by rotations, electives, and attendance at IR conferences, which will increase undergraduate awareness and promote IR as a career.

Revitalizing Urban Governance: Integrating Smart Growth and Decolonial Perspectives for Municipal Empowerment in Shaping Growth Across Egyptian Desert Landscapes
Authors: Alhowaily Anas
Published: December 2023

This article explores the connection between Smart Growth and the decolonization of urban growth management in Egypt, examining the impact of former colonial influence on present urban policy and practices. Drawing insights from the urbanization of Egyptian desert areas before and after the New Urban Communities Program (NUCP), it scrutinizes how historical influences adversely affect contemporary approaches, inducing socio-economic impacts. The primary objective is to identify the root causes of misguided urban growth management practices, arguing that mono-institutional and sectoral development is rooted in Egypt's quasi-colonial history preceding the NUCP. The research employs a comprehensive methodological approach, using descriptive qualitative methods to investigate the growth of emerging cities based on Smart Growth principles and quantitative analysis to assess population decongestion resulting from the NUCP. It evaluates the implementation of Smart Growth principles during the NUCP and pre-NUCP, offering insights into adverse management practices. Despite the NUCP's goal to alleviate congestion, only 1.6 percent of the population was decongested by 2017. The research highlights the need for a new municipally guided growth model, emphasizing indigenous and locally validated approaches. This model aims to rectify inefficiencies in current urban management practices, fostering a responsive and sustainable approach aligned with local community needs.

Objective: Since the 1930s, a variety of resins have been introduced into dent al treatments for the construction of dental prostheses and their efficacy has been based on physical, chemical and biological properties. Denture breakage is usually related to faulty design, faulty fabrication, and/or poor materials choice. Purpose: of this study is to investigate (in vitro) the fatigue bond strength and impact bond strength of the denture repaired by light-cured acrylic resins by using different chemical solvents such as acetone, m onomer and thiner. Materials and methods: The acrylic resin used are heat-cure, specially designed molds are use to prepare 6 groups of specimens following the manufacturer's instruction (5 specimens for each cured polymerization). Specimens were cut in guiding by standardized positional jig. The ends of specimen saturated by different solvents acetone, thiner and monomer before repairing. To evaluate the impact strength, plastic strips were fabrica ted as per the dimensions (50×5×4) mm. Alternating bending fat igue machine was used to test the ten samples with the dimens ion of (70102.5) mm. Result: impact bond strength with m onomer solvent higher than thiner solvent and acetone solvent. Fat igue bond strength with acetone solvent higher than thiner solvent and monomer solvent. Acetone, thiner and monomer were appl ied as solvents, the results of all surface treatments revealed signi ficant difference at (P- value <0.05) in mean value (no signi ficant for fatigue bonde strength but significant with impact bond strength.

Problem: Acrylic dentures frequently fracture during service due to their poor strength characteristic. Several attempts have been carried out to improve strength of acrylic by addition some materials such as fibers or Aluminum oxide. The purpose of this study was to evaluate the effect of adding Aluminum oxide (AL2O3) on the surface roughness and hardness of heat cure acrylic resin denture base material. Materials and Methods: 60 specimens were made from the heat cure acrylic resin denture base after being cured in microwave oven, 30 specimens prepared for surface roughness test and these where subdivided according to concentration of AL2O3 into three subgroups as follow: Group (A): 10 specimens of acrylic resin without AL2O3 (control group) Group (B): 10 specimens of acrylic resin+2.5% by weight AL2O3 Group (C): 10 specimens of acrylic resin +5% by weight AL2O3 30 specimens prepared for surface hardness test and these where subdivided according to concentration of AL2O3 into three subgroups as follow: Group (A): 10 specimens of acrylic resin without AL2O3 (control group) Group (B): 10 specimens of acrylic resin+2.5% by weight AL2O3 Group (C): 10 specimens of acrylic resin +5% by weight AL2O3 The average of the surfac e roughness of the samples has been determined with using the profilometer (surface roughness tester)¸ also the average of the sur face hardness of the samples has been determined with using surface hardness tester (digital micro Vickers). Result: The results show ed that there were no statistically significant differences in t he surface roughness and hardness. Conclusion: The addition of aluminum oxide in low percentage not affected on the surface roughness and hardness of heat cure acrylic resin.

Authors: M. Yahya Maha
Published: December 2023

Perforation of the root canal system is the second large cause of root canal failure. Fa ilure to seal the perforation defect permits rapid break-down of the periodontium and tooth loss. Hence sealing the defect is paramount. Aims: This study was conducted to evaluate the sealing ability of a new material, self-setting dentine substitute (Biodentine) in furcation perforations and compare it with Mineral trioxide aggregate and glass ionomer cement. Materials and Methods: Fifty five (55) recently extracted permanent lower molars with non-fused well developed roots were collected and intentional perforations were made in the furcation area with a bur. The perforations were repaired with Biodentine for group( A) ,mineral trioxide aggregate (MTA) for group (B) and glass ionomer cement(GIC) for group (C). The specimens were then immersed in 2% methylene blue dye for 48 hour. After their removal, they were sectioned and examined under stereo microscope to evaluate dye penetration. Results: demonstrated that furcat ion perforation repaired with Biodentine showed least microleakag e. Conclusion Biodentine demonstrated better results than MTA and GIC.

Authors: M. Yahya Maha
Published: December 2023

Aims: The aim of This study was to evaluate the effect of some endodontic irrigants on the push-out bond strength Biodentine in comparison with M ineral trioxide aggregate (MTA) and Glass ionomer cement (GIC).Materials and Methods: Mid root dentine of single rooted teeth was horizontally sectioned into 1-mm-thick slices. The canal space of each dentine slice was enlarged with a diamond bur to 1.4 mm in diameter. The samples were divided into 3 groups (n=21)for each, and the following materials were placed, respectively: Biodentine( Septodont, Saint Maur des Foss'es, France),MTA(Dentsply, TulsaDental, Tulsa, OK),and GIC(Medifil, PRO MEDICA, Germany).The samples were wrapped in wet gauze for 30 minutes to ensure setting of the materials and then divided into 3 subgroups (n=7)for each, to be immersed into QMix ((Dentsply Tulsa Dental, Tulsa, OK, USA), Bio Pure MTAD (Dentsply Tulsa Dental),and saline solutions for 30 minutes. No irrigant was placed over any test material in the other three subgroups. After incubation for 48 hours, the dislodgement resistance of the samples was measured (with and with exposure to the irr igant solutions) using a universal testing machine. Then the samples were examined under stereomicroscope to det ermine the nature of the bond failures. Results: The lowest push -out bond strength was observed in the MTA group. Biodentine displayed a significantly higher resistance to displacement than t he MTA group. Exposure to QMix, MTAD, and saline solutions did not affect the resistance to displacement of the Biodentine and GIC groups, whereas MTA lost strength after exposure to the irrigant solutions ,but the difference was not significant. Conclusions : The PBS of Biodentine and GIC was not affected by the irrig ant solutions. Contact with the irrigant solutions did not have a significant effect on the failure modes of the tested materials
