AI-Based Secure Undergraduates’ Ideological and Political Public Opinion Strategy

The popularity of the internet makes everyone have the right to speak.People are no longer passive receivers of information but propagators of information, and for this reason, cyber opinion comes into existence.Some social events that can arouse people’s sympathy and are related to people’s vital interests will eventually form cyber opinions through netizens’ comments, discussions, and forwarding.As members of the society, undergraduates have different interests, political tendencies, and social cognition.When making judgments and comments on controversial hot issues, undergraduates will make their own correct judgments of authenticity according to their own knowledge and social experience, which will make the propagation content of public opinion more diversified.Especially for ideological and political public opinion, it is very important to ensure the safety of the public opinion propagation model intelligently.In this paper, first, cellular automata (ca) of artificial intelligence (ai) is used to establish the propagation model of undergraduates’ ideological and political safety public opinion and the stochastic immune mechanism model is introduced.Then, a ca-based stochastic immune mechanism model is adopted to simulate the real propagation process of undergraduates’ ideological and political public opinion.Finally, the experimental results demonstrate that the moving probability of public opinion subjects has a great impact on the propagation speed and homogenization rate of cyber public opinion and the proposed ca model can well describe the actual propagation process of cyber public opinion.Meanwhile, the proposed propagation model can ensure the propagation of undergraduates’ ideological and political public opinion on safety.

Sensory Integration Training and Social Sports Games Integrated Intervention for the Occupational Therapy of Children with Autism

This paper presents a research design for an integrated intervention using sensory integration training fused with social sports games for the treatment of children with autism.This study used a multiple baseline cross-subject design in a single-subject experiment, with structured play as the independent variable and expressive language skills of children with autism spectrum disorders as the dependent variable, with three phases of intervention: baseline, intervention period, and maintenance period.The expressive language ability was examined in terms of both oral expression and gestural expression, where the intervention effect of the oral expression was analyzed in terms of four components: the total number of words, the total number of sentences, average sentence length, and vocabulary complexity of oral expression, and the intervention effect of the gestural expression was analyzed in terms of changes in the frequency of children’s gestural expression behaviors.For the categories classified by sensory integration ability, there are corresponding specific training programs that combine various physical exercises and play equipment to train the various abnormal functions of children with autism.Stereotyped behavior is a repetitive, self-imposed, and purposeless physical action, usually in the form of continuous and repetitive movements, sounds, and so on.4 times a week, 25 minutes each time, the activity of recognizing pictures and familiar objects is carried out first, and then the children choose the structured game model and the initiative to build and take turns with the researchers to build.Stereotypic behaviors cause a great deal of distress in the lives of children with autism, and it is necessary to explore how to implement positive and effective interventions.Subjects’ play abilities developed after receiving effective critical response training.The subjects’ practice and symbolic play showed good immediate and maintenance intervention effectiveness; their associative and functional play showed no significant intervention effectiveness.The enhancement of the sensory integration skills of children with autism through sensory integration training resulted in a relative reduction of stereotypic behavior about the stimulus-seeking function, which had a positive effect on the intervention of stereotypic behavior.

The Effect and Mechanism of Exercise Training on Rats with Poststroke Depression Based on the Intestinal Flora

Depression of poststroke depression (psd) is the most common neuropsychiatric complication after stroke.Patients with psd had higher mortality, more cognitive disorder, lower quality of life, and higher suicidal tendency.The pathogenesis of psd mainly involves neurotransmitter inflammatory factors, hpa and bdnf.Enteral dysfunction and intestinal flora disorders caused by stroke can participate in the pathogenesis of psd through various ways, such as immune, endocrine, and nervous system.In this experiment, we used exercise training as an intervention means to explore the curative effect and possible mechanism by observing the changes of behavior, inflammatory factors, and intestinal flora in rats.The results show that the mechanism of exercise training to improve the depressive behavior of rats may be related to inhibiting the expression of proinflammatory factors and increasing the number of lactic acid bacteria in the intestine.
