Concerning The Use of Social Software on Constructivist Classroom Characteristics:Case study; Smart school

The research aimed to study the effects of social software application on constructivist classroom Characteristics. Applied research and descriptive - survey was conducted. The population consisted of all male and female teachers in the smart high schools that were selected by random sampling, 103 of them were selected as participants. The research's tool is scale of constructivist classes based on e-learning model Mvvdly and scale of social software applications. The reliability and validity of tools was calculated using the Cronbach's alpha and internal consistency. The method for data analysis, average fixed, correlation and regression analysis and structural equation modeling was conducted. The results showed that the use of social software and constructivist classroom Characteristics in the sample studied is higher than average. The use of social software and constructivist classroom Characteristics are taught positive and significant relationship. The results of regression analysis and path analysis showed that the use of the Internet and intranet affect on constructivist classroom Characteristics

Controversy and Consensus on Indications for Sperm DNA Fragmentation Testing in Male Infertility: A Global Survey, Current Guidelines, and Expert Recommendations

Purpose: Sperm DNA fragmentation (SDF) testing was recently added to the sixth edition of the World Health Organization laboratory manual for the examination and processing of human semen. Many conditions and risk factors have been associated with elevated SDF; therefore, it is important to identify the population of infertile men who might benefit from this test. The purpose of this study was to investigate global practices related to indications for SDF testing, compare the relevant professional society guideline recommendations, and provide expert recommendations. Materials and methods: Clinicians managing male infertility were invited to take part in a global online survey on SDF clinical practices. This was conducted following the CHERRIES checklist criteria. The responses were compared to professional society guideline recommendations related to SDF and the appropriate available evidence. Expert recommendations on indications for SDF testing were then formulated, and the Delphi method was used to reach consensus. Results: The survey was completed by 436 experts from 55 countries. Almost 75% of respondents test for SDF in all or some men with unexplained or idiopathic infertility, 39% order it routinely in the work-up of recurrent pregnancy loss (RPL), and 62.2% investigate SDF in smokers. While 47% of reproductive urologists test SDF to support the decision for varicocele repair surgery when conventional semen parameters are normal, significantly fewer general urologists (23%; p=0.008) do the same. Nearly 70% would assess SDF before assisted reproductive technologies (ART), either always or for certain conditions. Recurrent ART failure is a common indication for SDF testing. Very few society recommendations were found regarding SDF testing. Conclusions: This article presents the largest global survey on the indications for SDF testing in infertile men, and demonstrates diverse practices. Furthermore, it highlights the paucity of professional society guideline recommendations. Expert recommendations are proposed to help guide clinicians
