The application of Statistical Modelling techniques so called as Stractural Equation Modelling (SEM) to an industrial case, is the main objective of this paper. SEM is a powerful modeling technique that can combine complex path models with latent variables (factors). The basic elements involved in SEM, like factor analysis specially confirmatory kind of it, are illustrated. In a Modelling process the conceptual framework of The Impact of CAD/CAM/CAE Virtual Integration on Organization(s) Survival is modeled using SEM. The developed model is tested on using the data from automative manufacturing organizations of IRAN. Symbolic presentation of the theoretical model and testing is done using one of the powerful software of SEM called LISREL.

The purpose of this study was Structural Equation modeling (SEM) of anomalies incidence of soccer fans in Iranian stadiums. The present study was applied in terms of purpose and in terms of collecting data, a descriptive correlation type was used (qualitative-quantitative). In the beginning, studying the literature and conducting a qualitative interview with 17 specialists, the basic concepts of the occurrence of abnormalities in the stadiums of the country were formed; further analyzing the contents of the interviews and literature of the field, 47 items were discovered, distributed among 30 fans at Azadi Stadium, the reliability coefficient of the initial questionnaire was 0. 783. Regarding the number of samples over 200, for Structural modeling, including 20 percent reduction, 250 questionnaires in Ghadir Ahwaz, Azadi, Rasht, Azadi Tehran, Takhty Jam and Emam Tabriz as inflammatory stadiums in the sixth week of the Premier League, which ultimately won 221 The questionnaire was used; after examining the KMM and the orthogonal rotation of the data for the exploratory factor analysis, prepared from among the 45 items in the 36 items with a factor load above 0. 3 and analyzed for the confirmatory factor analysis; Finally, the data were used using the Structural modeling method (LISREL). According to the coefficients of influence, the ultras (0. 67), the conditions of the stadiums (0. 60), cultural conditions (0. 44), The security conditions (0. 37) were management status (0. 20). Finally, with regard to the presence of the leaders in the form of a fan base, as the main point of stimulation and stimulation of fans as the most coefficient component, the training needed to manage the platforms in this group, along with the use of qualified people in this position, is more than necessary.

Objective: The aim of the present study was to assess factors affecting behavioural management of dental anxiety among dental students. Methods: The present study was conducted on 218 dental students of Ahvaz Jundishapur University of Medical Sciences, Ahvaz (AJUMS), school of dentistry, Iran during 1 to 21 November 2020. The data collection tool included a self-designed questionnaire containing a number of questions for assessing students’,anxiety reduction guidelines, and behaviouralmedication anxiety control methods, as well as measuring key components of the Theory of Planned Behaviour (TPB). The layout of the questionnaire and all its questions/items were designed on the website https: //survey. porsline. ir. Data were analysed using SPSS, version 23. The Structural Equation Modelling (SEM) was performed using AMOS software version 26. 0. Results: A total of 246 dentistry students were invited to participate in the study. Out of 246 students enrolled, 218 (88%) students completed and sent the questionnaire. The results revealed that behavioural intention had a direct impact on the implementation of distinguished instructions. Likewise, subjective norms and perceived behavioural control directly influenced the behavioural intention. The fit indices indicated that the measurement might have an acceptable performance (GFI , = , 0. 86, CFI=0. 81 RMSEA , = , 0. 07, x 2 > /df 3),R2=0. 37. Perceive behavioral control and intention were the most important factors in explaining dental anxiety control behaviour. Conclusion: The findings suggest that the constructs of the theory of planned behaviour might have a preliminary acceptable fit for determining the factors related to the beliefs and behaviours of dental anxiety control. Further studies are needed to improve model fit indices. The future studies should determine which educational methods could better manipulate the predictive factors.

This study aimed to investigate the effects of neuroticism, as one of the big five personality factors, on oral performance and its components comprising cohesion and fluency, pronunciation, grammaticality, and lexical resources. To this end, 257 Iranian EFL students took an oral proficiency interview (OPI) and responded to a personality questionnaire including 50 items (Goldberg, 1992). The participants' oral performance was rated by two trained raters. The Structural Equation modeling (SEM) analysis, revealing the standardized non-direct effects of neuroticism on the components of speaking, showed that neuroticism had moderate and negative indirect effects on cohesion and fluency (Beta =-. 351), lexical resources (Beta =-. 365), grammaticality (Beta =-. 354), and pronunciation (Beta =-. 350). The results of the study are discussed and the pedagogical implications are provided for the EFL context.

The aim of this study was to investigate the Structural relationship among Behaviouralinhibition system (BIS) and Behaviouralactivation system (BAS), dispositional mindfulness and alexithymia. For this reason, in a descriptive-coorelational and retrospective study, 180 university students were selected from Tabriz University by convenient sampling method and asked to answer TAS-20, FFMQ and BIS/BAS scale. Results showed that behavioural inhibition system has sinificantly positive and direct effect on dispositional mindfulness and alexithymia.There is not significant relationship between dispositional mindfulness and alexithymia. The indirect effect of behavioural inhibition system and behavioural activation system on alexithymia is not significant. According to the results, the behavioural inhibition system is the important determinants of mindfulness and alexithymia. Also, the tested model able to explain alexithymia in normal people.
