The flat-plate momentum test bench is a widely used experimental device in the verification of the momentum law of fluid mechanics, and its error characteristics are of positive significance for theoretical research and engineering innovation and expansion. The SPH-FEM coupling algorithm and spectrum analysis method are used to calculate and analyze the displacement response and spectrum characteristics of the characteristic points of the sensor under different jet loads. Based on them, the cause, classification, law, scope, influence and control method of the measurement error of the system are discussed and analyzed with the application of the error theory and the lateral effect theory of strain gauges; combined with physical experiments, the relevant analysis methods and conclusions are verified. The results show that the measurement error of the system includes linear error and periodic error. Structural deformation in the direction of jet impact is the main source of linear error; linear error increases with the increase of jet loads. Meanwhile, periodic vibration in non-jet direction is the main cause of periodic error, and the periodic error decreases with the increase of jet loads.

Research in Western countries has demonstrated that marriage is associated with improved well-being, and parenthood with decreased well-being, for both men and women. However, less is known about whether the associations are universal for both genders across countries. Using nine waves of panel data and fixed effects models, this study examines the relationship between changes in family roles and subjective well-being of men and women in the highly gendered social context of Japan. Well-being was assessed across two domains: self-rated health and mental health. The results broadly support the protective effect theory, which posits that marriage itself has a positive effect on well-being; however, no association was observed between becoming a wife and self-rated health. Contrary to what previous research predicts, only men’s self-rated health negatively responds to transition to parenthood. These findings highlight the importance of country context and gender differences in the significance of family obligations.

Regulatory fit theory is based on regulatory focus theory which was from hedonism and decision-making motives, explaining individual consumer’s decisions making processes from both psychological and mental point of views. Regulatory fit theory proposed consumers in the face of different forms of information representation will lead to match or mismatch of consumer wants. And the effect of adjusting the matching value will affect the perception of the product or service, thereby affecting the consumer’s buying wish.Framing effect is originated from prospect theory indicate that people will make different choices when they face the same, but different forms of expression scheme. This article tries to explore the inherent nature of impulsive buying behavior mechanisms, drawing on regulatory fit theory and framing effect theory.

Aerodynamic support is beneficial for achieving very high speeds of marine transportation. Wing-in-ground vehicles, power-augmented ram platforms, and ultrafast planing multihulls are examples of marine craft with air assistance. The main technical problems in the development and application of these concepts for marine transportation are to ensure motion stability and to provide adequate seaworthiness. In this article, we illustrate applications of several mathematical models for various air supported marine vehicle concepts and discuss their specific stability issues. The aerodynamic submodels are based on nonlinear vortex-lattice methods and on the extreme ground effect theory, whereas unsteady hydrodynamics of planing surfaces are treated with added-mass strip theories. The static and dynamic stability in the vicinity of equilibrium states can be analyzed by linearized approaches. However, motions in transient regimes and unsteady environments require implementation of nonlinear and fully unsteady modeling methods.

Sex education is still a topic that is considered taboo in Indonesia, through Tiktok which is a popular application in the world in 2020, it is used as a medium to meet this information need by the @tabu.id account. The purpose of this study was to determine the effect of intensity, media content and attractiveness of using social media on the TikTok @tabu.id account on the fulfillment of sex education information needs. This study uses a quantitative approach with an explanatory survey. The theory used is the Uses Effect Theory. The data collection technique used is a questionnaire or questionnaire and literature study. While the data analysis technique will be collected using a Likert scale. The results of this study are the intensity, message content and attractiveness affect the need for information about sex education. While the magnitude of the influence of sex education information is 6.75%, the magnitude of the influence of infographic messages on sex education information is 33.26% and the magnitude of the influence of sex education information is 15.02%.
