Abstract-Internet and Social media is a ubiquitous phenomenon affecting many areas of life, including education. From various disciplines have used some forms of social media in their personal as well as professional lives, the English Language Teaching (ELT) teachers are no exception. Many studies on the area have been conducted such as those reviewed by Inayati (2013), and Tess (2013). However, despite the fact that Iran is among the high users of a number of social media, such study in Iran is still scarcely found in International journals. Therefore, this paper addresses the issue by studying how Iranian ELT teachers perceive social media in relation to their teaching as well as their general attitudes towards this type of media. A number of ELT teachers in recent popular social media (telegram, whatsapp) were surveyed with regards to their attitude and perception of social media use in teaching English. Analysis of the survey results showed that generally, the participants indicated positive attitude towards the employment of social media in ELT. In addition, most participants also showed high awareness of the educative potentials offered by social media in ELT practices, and several factors which could potentially hinder the actual use of social media were also identified. Some implications were drawn based on the findings of the study, some of which are related to the aspect of education management.

The present article is about language and power, focuses on the speechmaking skills, and using persuasive techniques such as Simile and metaphor, Mixed metaphor or simile, Extended metaphor, Allusion, Lists of three, Repetition, Parallelism, Puzzled or redundant questions, Alliteration and Wordplay. For the sake of better analysis certain elements of this ability, a comparison between Iran President Mr. Rouhani and U. S. President Mr. Obama is made. Two speeches of two presidents are selected. The first two are in the same topic and the second two are in different topics. Each president is a strong personality in his own right, both leaders have manifested this ability and managed to persuade the masses about the correctness of their political steps; however their using of persuasive techniques differ dramatically, as it is attempted to support by analysis in this article. The results show that, usually they use the same techniques but Dr. Rouhani use more persuasive techniques than President Obama does. Dr. Rouhani uses Alliteration and President Obama uses Metaphor more than other techniques in their speeches.  It can be said that using persuasive techniques is culture based.

Purpose:The purpose of this study was to investigate the relationship between anthropometric indices and lipid profile in-office employees.Methods: This descriptive study was performed in Tehran, Iran. In total 294 office employees (166 males and 83 females) participated as samples study in this research. Blood samples (TC, TG, HDL-C, LDL-C and LDL-C to HDL-C ratio) were taken from the brachial vein in sitting position and fasting state. Then anthropometric indices includingbody mass index (BMI), waist circumferences (WC) and waist-hip ratio (WHR) were measured and recorded. All statistical analyses were conducted with "SPSS 21". Results: There was a positive and significant correlation between TG and LDL-C/HDL-C ratio with BMI, WC and WHR. There was also a direct and significant correlation between WHR and LDL-C. On the other hand, there was an inverse correlation between HDL with BMI, WC and WHR. Moreover, anthropometric indices (BMI, WC and WHR) were significantly higher in the older group than the younger group. Also, triglycerides, LDL-C and also, BMI, WC and WHR were significantly higher in men than women; but, HDL-C was significantly higher in women. Conclusion: Regarding the association of anthropometric indices with lipid profile and its significant differences across age and gender groups, these parameters can be used to evaluate and screen cardiovascular and metabolic disease-related risk factors.

Purpose:The aim of this study was to investigate lipid profile and hepatic enzymes difference between pre-diabetes and normal subjects.Methods:In this cross-sectional study, 264 employees of Energy Industries Engineering & Design (EIED) Company were randomly selected and participated in the study in January 2019.A sample of 10 mL of venous blood was obtained between 8 a.m. and 10 a.m. Blood analyses for fasting glucose (FG), total cholesterol (TC), triglyceride (TG), LDL-cholesterol, HDL-cholesterol, aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP) levels were determined by enzymatic methods. Body composition and anthropometric indices were measured and recorded using the OMRON BF511 device and tape measure.Achievements of This Study:TG, the LDL/HDL ratio, and the ALT were significantly higher in the pre-diabetes group. Also, body mass index, waist circumference, waist-hip ratio were significantly higher in pre-diabetic women than in normoglycemic women.According to the results of this study suggested that the risk of cardiovascular and liver diseases in people with pre-diabetes increases and the intervention of lifestyle such as increased levels of physical activity and exercise to prevent diabetes and related complications.

Purpose:The purpose of the present study was to investigate the differences between diseases, geriatric syndrome and medication use among sedentary and active community-dwelling elderly in Tehran.Method:In this cross-sectional study, 465 community-dwelling elderly men aged 60-95 living independently in Tehran city, Iran participated voluntarily. After the evaluation of PA (physical activity) levels, subjects were divided into two (active elderly and sedentary elderly) groups. Then age-related geriatric syndromes and diseases were measured by questionnaires and functional tests. Data analysis was performed using SPSS(Statistical Package for the Social Sciences) statistical software version 21 and p-value of <0.05 was considered to be statistically significant.Achievements of the study:The result of T-test showed that compared with sedentary participants, highly active individuals had better life expectancyand lower risk of fall and sarcopenia (p<0.01). In relation to comorbidities, the number of diseases in physically active individuals was the same as men in sedentary group (p>0.05).It can be stated that higher PA level plays an effective role in the improvement of many age-related disorders and successful aging.
