Purpose: The future of the construction industry is increasingly influenced by new technologies. In order to adopt appropriate strategies in facing new technologies, it is necessary to know the possible futures of the construction industry. This research was done with the aim of explaining the technological uncertainties and compiling the future scenarios of the construction industry.  Method: The research method is applied and was carried out with a combination of quantitative and qualitative methods. First, the library study was used to determine the technological drivers, then the Structural Analysis was used to explain the technological uncertainties, and finally, the Schwartz method was used to compile the scenarios. The statistical population is experts of construction industry. Findings: Nine technological uncertainties affecting the future of the construction industry have been identified and for each of them, three states of decline, stagnation and progress have been considered. Data analysis by Scenario Wizard shows eight probable scenarios. The portfolio of scenarios including four groups of progress scenarios, towards progress, towards stagnation, and towards wane has been compiled. Conclusion: In the progress scenario, the 89% of uncertainties have developed. In  towards progress, 56% of the factors are in the development status, which indicates the development of the technological factor application. In the stagnation scenario, no progress has been made in the application of uncertainties and they are in a static state. In towards wane, uncertainties have been placed in a situation of reduced use.

Background: The expansion of the use of audio and video media technology has faced society with many medical, cultural and economic challenges. In the meantime, excessive use of mobile phones can cause many problems. Objective: The aim of this study was to construct and validate a questionnaire on physical and psychological injuries of mobile phones. Method: The method of the present study was descriptive-correlational and confirmatory factor analysis. The statistical population of the study consisted of all citizens of Khorramabad with a diploma or higher in 1399, which was selected as a statistical sample by available sampling method of 200 people online and virtual. Results: The results showed that the factorized physical and psychological harm questionnaire of cell phone with 42 questions and 10 components (fear of loss, vibration syndrome, duck syndrome, nomophobia, insomnia, hearing problem, eye syndrome, tunnel and neck syndrome SMS) and has good reliability, validity and flexibility in terms of psychometrics. Discussion and Conclusion: The questionnaire of factor analysis of physical and psychological injuries of mobile phones can be used to identify and study the physical and psychological injuries of mobile phones.

We use the ultramean construction to prove linear compactness theorem. We also extend the Rudin-Keisler ordering to maximal probability charges and characterize it by embeddings of power ultra- means.

This study aims to investigate the focus construction and its markers in Kalhori Kurdish. It should be noted that focus is shown with phonetic, morphologic or syntactic markers in different languages. The data were collected through observation and interview with Kalhori Kurdish speakers in Kermanshah. The findings showed that the focus markers in Kalhori Kurdish include /ke/ and /xo/ used in the same sense. Moreover, it was found that although these two focus markers have the same meaning, their usage varies in different declarative, imperative, interrogative (yes/no questions & wh-questions) and exclamatory sentences. However, in exclamatory sentences the speakers use none of these two markers to show emphasis. The results indicated that although the speakers use both focus markers in declaratives and yes/no questions, /ke/ is simply used in imperatives and wh-questions. Also, the research findings showed that /ke/, as a focus marker, is used less than /xo/.

The present paper aims at investigating the imperative paradigm in Kurdish language by drawing on two criteria, namely formal homogeneity and minimality/maximality. The results show that Kurdish language specifies morphological imperative constructions just for second persons; and expressing any commandment directed at non-second persons requires analytical constructions (4 constructions). By scrutinizing the heterogeneous imperative constructions in Kurdish, the paper shows that Kurdish has an imperative paradigm characterized by a minimal system without any maximal counterpart. Also, the canonical imperative construction in Kurdish is specified by some characteristics including temporal distinctions and different prefixes for prohibition and negation. Finally, the paper tries to explain semantic aspects of different imperative constructions in Kurdish by considering two criteria of second person subject and force exertion. The results show that the canonical imperatives include most of the semantic features of the prototypical imperative category; whereas, the non-canonical ones lack most of these semantic aspects.
