Toxic and repellent effects of the essential oil from Asarum heterotropoides Fr. Schmidt var. mandshuricum (Maxim.) Kitag. were evaluated against Lasioderma serricorne and Liposcelis bostrychophila. The essential oils (EOs) from roots (ER) and leaves (EL) of A. heterotropoides were obtained separately by hydrodistillation and characterized by gas chromatography-mass spectrometry (GC-MS) analysis. Major components of ER and EL included methyleugenol, safrole, and 3,5-dimethoxytoluene. Both ER and EL of A. heterotropoides showed certain toxicity and repellency against L. serricorne and L. bostrychophila. 3,5-Dimethoxytoluene, methyleugenol, and safrole were strongly toxic via fumigation to L. serricorne (LC50 = 4.99, 10.82, and 18.93 mg/L air, respectively). Safrole and 3,5-dimethoxytoluene possessed significant fumigant toxicity against L. bostrychophila (LC50 = 0.83 and 0.91 mg/L air, respectively). The three compounds all exhibited potent contact toxicity against the two insect species. Here, the EL of A. heterotropoides was confirmed to have certain toxicity and repellency against stored product insects, providing a novel idea for the comprehensive use of plant resources.

This research discusses the impact of the perception of video images and online word of mouth on tourists’ travel intentions. A survey of 390 users who watched travel videos on short-video platforms was conducted using structural equation modeling. The results are as follows. First, the perception of video images can significantly affect tourists’ intention to visit the destinations. Second, as a mediating variable, online word of mouth can enhance the positive effects of the perception of video images on tourists’ travel intentions. Third, gender had a positive moderating effect, which was particularly obvious in the relationship between the perception of video images and online word of mouth. This research provides a theoretical basis for the utility of tourism-related short videos, which can help stimulate tourists’ intention to visit promoted destinations.

After analysis of the data from Dalian bus IC card database, the paper propose an optimization algorithm for bus scheduling. By introducing an artificial immune algorithm based on information entropy, the optimal or the quasi-optimal solution to this multi-variable and non-linear problem of bus scheduling can be found efficiently. The experiment results demonstrate that the optimal bus departure intervals under different time periods can be obtained to adjust bus timetable conveniently, which help to adjust bus timetable dynamically.

Carbon fibers reinforced lithium aluminosilicate matrix composites (C f /LAS) were prepared by slurry infiltration combined with a hot press procedure. The friction, wear behavior, and wear mechanisms of C f /LAS composites under dry sliding conditions were investigated. The results show that the coefficient of friction (COF) initially increased with the increase in carbon fiber content, and reached the maximum value of 0.20 for the 33%C f /LAS composite. The COF increased sharply with increasing sample temperature from RT to 300 °C. The COF remained stable in the temperature range of 300-500 °C. The two wear mechanisms of LAS glassceramics are fatigue wear and abrasive wear. The C f /LAS composites demonstrate slight spalling and shallow scratches. These results show that carbon fibers improve the mechanical properties and wear resistance of C f /LAS composites.

The main aim of this study is to develop and test a comprehensive model that can predict the tourism intention of potential wellness tourists. The study also investigates the mediating effect of attitude and discusses differences in the behavioral intentions of potential wellness tourists between China and South Korea. The data were collected via questionnaire surveys, and structural equation modeling was used as an analysis tool. The results reveal that perceived susceptibility and perceived benefits can significantly, positively influence the behavioral intention of potential wellness tourists in South Korea, while perceived barriers have a negative impact on that of potential wellness tourists in China; in both samples, perceived susceptibility and benefits can have a positive impact on attitude. Moreover, in South Korea, attitude had a significant mediating effect among perceived susceptibility, perceived benefits, and behavioral intention. This study enriches and expands the literature on the behavioral intention of potential wellness tourists, use of the health belief model (HBM), and the theory of planned behavior (TPB), and provides a theoretical basis as well as a scientific decision-making reference for wellness tourism management and relevant stakeholders.

On the basis of the bottom-up spillover theory, this study explores the influence of the wellness tourism experience on tourists’ well-being. Considering wellness tourists as the research participants, tourist satisfaction, gender, and age were selected as the mediating and moderating variables, respectively, to study the mechanism between the wellness tourism experience and tourist well-being. A questionnaire survey was sent to 445 participants who engaged in wellness tourism in China, and an empirical analysis was conducted using the structural equation model. The results showed that the entertainment, esthetic, and escape experience of wellness tourism can significantly affect tourists’ hedonic and eudaimonic well-being. Tourist satisfaction, as a mediating variable, can enhance the positive impact of the wellness tourism experience on tourist well-being. Moreover, gender and age have a significant moderating effect on the relationship among wellness tourism experience, tourist satisfaction, and tourist well-being. This study enriches the current scholarship in the fields of the wellness tourism experience and tourist well-being and provides a theoretical basis and scientific decision-making reference for wellness tourism enterprises and tourism management departments.
