In order to analyze the consumption decision-making behavior of Comic Con tourism, based on SPSS, a questionnaire of consumer decision-making behavior of Comic Con tourism was designed to evaluate the demographic characteristics, decision-making behavior, actual consumption behavior and consumption effect of consumers. The results show that the comic exhibition tourists are mainly young people aged 18-24, who prefer social platforms to obtain information, pay attention to exhibition services and city image, and put forward suggestions on strengthening social media marketing, improving exhibition service quality, improving city image and tourism environment, strengthening the content and activity arrangement of comic exhibition, and promoting the sustainable development of comic exhibition tourism, which is of great significance for promoting comic exhibition tourism.

To investigate the driving effect of the digital economy on tourism development in Southwest China, this study employs linear regression analysis. Taking Southwest China as the research subject, we constructed a multiple linear regression model incorporating digital economy indicators (including software business revenue, mobile phone penetration rate, and e-commerce development) and tourism development indicators (domestic tourism revenue and domestic tourist arrivals), followed by empirical testing. The results demonstrate that the following indicators significantly and positively impact tourism development in Southwest China: proportion of IT professionals in urban areas, mobile phone penetration rate, broadband internet user ratio, enterprise computer adoption rate, e-commerce......

Based on the existing problems in the current research on BaShu cultural tourism decision-making, we propose a research approach for the application of data mining algorithms in BaShu cultural tourism decision-making. Firstly, a deep learning based model of BaShu cultural tourism and related tourist attraction attributes is constructed. Based on this, a tourist group behavior model based on spatial temporal mining is constructed, and a BaShu cultural tourism spatial layout and tourist accurate matching model are proposed. Finally, a BaShu cultural tourism route decision-making model is designed. The method we constructed can provide a basis for recommending BaShu cultural tourism attractions, planning BaShu cultural tourism routes, and making BaShu cultural tourism decisions.

Keywords: Data mining, BaShu culture, tourism decision-making, application research.

This paper presents an algorithm for determining the desired transition point from the autonomous flight phase to the homing phase while satisfying predefined conditions. The requirements at the end of the autonomous flight phase include ensuring the appropriate homing distance and aligning the missile velocity vector with the missile-target line of sight. The analysis is conducted for a target moving with constant velocity and different initial heading angles, where the missile trajectory follows a Rayleigh function. The results indicate that the proposed algorithm meets the specified requirements.

Keywords: Autonomous Flight Phase, Transition Point, Missiles guidance, Rayleigh function.

Ergonomics plays a critical role in industrial product development, enhancing user comfort, efficiency, and safety within the paradigms of Industry 4.0 and 5.0. This literature review synthesizes ten studies from 2018 to 2024 to examine how designers integrate ergonomic principles into industrial product design. Employing a systematic methodology with SciSpace, an AI-driven platform, the review explores Human-Centered Design (HCD), advanced technologies, anthropometric data, and cognitive ergonomics. HCD prioritizes user needs, with 57% reduction in biomechanical stress through collaborative workstations........

Based on the characteristics of higher vocational education and the specific implementation process of classroom teaching, we introduce artificial intelligence method into the classroom teaching process of higher vocational education. The clustering method is determined to be an effective method for student interest mining, and the specific application of k-means method in student interest grouping is studied. An interest mining model is established. Taking tourism course as a case study, a classroom teaching model is designed by student interest grouping, providing decision-making reference for teachers to organize and implement seminar classes.........

This paper presents research results on the dependence of thrust generated by fixed-pitch propellers on rotational speed and airflow velocity from a wind tunnel. Variations in propeller thrust due to changes in rotational speed and airflow velocity (flight speed) directly affect propeller efficiency. The experimental setup provides reliable data to establish propeller thrust characteristics during the design and operation phases of UAVs utilizing propellers in both civilian and military aviation.

Keywords: Thrust, propeller, pitch angle, rotational speed, airflow velocity, aerodynamics.

Dyslipidemia is a condition of imbalance of blood lipid levels, which increases the risk of coronary heart disease and stroke. Causative factors include a diet high in fat and fructose, a sedentary lifestyle, obesity, and oxidative stress. Rosella flower (Hibiscus sabdariffa) is known to have potential as a natural therapy in the management of dyslipidemia due to its content of active compounds such as anthocyanins, flavonoids, and phenolic acids, which can lower total Cholesterol and triglycerides and increase HDL. This study aimed to evaluate the effect of ethanol extract of Rosella flowers on the blood lipid profile of Wistar rats fed a high-fat and fructose diet.........

The healing post-tooth decaying wounds is a vitaltissue regeneration stage involving fibroblast cell activity. Andaliman fruit (Zanthoxylum piperitum) contains bioactive compounds such as flavonoids and terpenoids that can accelerate healing through anti-inflammatory effects and stimulation of tissue regeneration. This study aims to determine the impact of andaliman fruit extract with a concentration of 30% and 60% on the number of fibroblasts in the healing process of wounds after tooth extraction in Wistar rats.........

Keywords: Andaliman, fibroblasts, post-tooth wounds, wound healing, Zanthoxylum piperitum.

Tooth extraction is a standard surgical procedure that can cause injuries to the surrounding tissues, which take time to heal. Post-tooth extraction wounds often affect patient comfort and can lead to complications such as infection, swelling, and dry sockets, which prolong the healing time. One of the increasingly popular approaches to speed up wound healing is using natural ingredients, such as garlic extract (Allium sativum), which is known to have anti-inflammatory, antibacterial, and antioxidant properties..........
