Aim: The present study was conducted to validate the international version of the resilience scale (CYRM-28) among adolescent youth students.
Methods: The first original scale was translated into Persian language by two experts. Then an integrated version of the two was translated to the language of the original version again; then it was ensured that the content of the Persian and English versions' was matched. The Persian version scale was filled in by 412 high school students (270 males and 142 females) in Tehran, who were selected as a random cluster. Regarding the clear scale structure to assess the validity, construct validity was used (confirmatory factor analysis) using the LISREL software version 8.8. In addition, scale reliability was examined using the two methods of internal correlation coefficient and test-retest.
Findings: Fit Index confirmed the resilience scales' fit ness in confirmatory factor analysis. In examining the reliability using the internal correlation calculation method (Cranach’s alpha), the value of each sub-scale item, as well as that of total questions was higher than the standard value of 0.7 to confirm the tool's reliability. In examining the reliability using test-retest method, correlation coefficient of each sub-scale in two steps was at an acceptable level and significant.
Conclusion: The present study confirmed the three-factor structure of CYRM-28 scale, including the individual sub-scale's relationship with the primary caregiver and contextual factors in the Persian version of the scale. This study showed that the reliability and validity of the Persian version of CYRM-28 was suitable for measuring the resilience of Iranian children and youth.

Aim: People receive social support from family, peers, and other social systems. Within this wide spectrum, social networks that support people unofficially involve the group of family and peers. The aim of this study was to determine the relationship between perceived social support and mental health of students in Tehran.
Methods: This descriptive and analytical study was conducted on 227 students in Tehran using two questionnaires including the General Health Questionnaire (GHQ-28) with 28 questions, and the social support inventory with two scales of Perceived Social Support from Family (PSSFA) and Perceived Social Support from Friends (PSSFR). The collected data were analyzed via SPSS18 software using Pearson correlation test.
Findings: The results showed that mental health had significant relationship with the total score of social support (p<0.05, r=0.197). Furthermore, concerning the other subscales, anxiety and sleep disorders (p<0.02, r=0.155) and social functioning (p<0.006, r=0.190) showed significant relationship with mental health. However, there was no significant correlation between PSSFR and mental health.
Conclusion: As proved by the results of this study, when social support is stronger, an individual will have a better mental health status. Moreover, people who experience a higher level of family support have a better mental health status.

This article analyzes the rate of electoral participation during ten periods of presidential election in Iran within 1979-2009. The rate of electoral participation in Iran’s presidential elections has been problematic and not based on a regular pattern of change. Having proved this claim, the theory of democratic political system was chosen as the theoretical foundation of the paper in order to find a solution to the problem. The problem was related logically to the theory and inspired by the theory, the research question was formulated. On the theoretical level, it was argued that there is a relationship between party competition and electoral participation such that by an increase in the extent of party competition, the electoral participation will also increase. This argument was put through a regression analysis. Available evidence indicates that there exists a 45% positive correlation between electoral participation and party competition.

Objective: Sea cucumber is a traditional food and medical item and has been reported to exhibit Antioxidant, antifungal, anti tumoral and antibacterial bioactivity. The objective of this study is to describe the antibacterial activity of 4 extracts of Holoturia. Sp (sea cucumber), collected from Hengam Island of Persian Gulf. Materials and Methods: Methanol, hexane, aqueous and chloroform extracts from body wall tissue of the sea cucumber were screened for antibacterial activity against three strains of Escherichia coli Top 10 F´, TG1 and K12 using disc diffusion and broth microdilution tests methods. Result: The growth of all these strains were inhibited using concentration from 0.78 to 100 mg/ml of methanol, hexan and chloroform extracts. Among the extracts just methanol and chloroform with 100 mg/ml had bactericidal effect on TG1 and K12 strains. On the other hand, Aqueous extract had induced growth in of the all strains. Conclusion: The results suggest the possibility of applying sea cucumber as source of potential anti bacterial agents, whose compounds can be good candidates to make antibiotic products.

Natural events and disasters always have a devastating impact on human settlements and incur economic and social effects on societies by destroying buildings and infrastructures. One of these destructive phenomenons is landslide that could damage communities, meadows and forests, communication lines, and monuments extensively in many parts of the globe, especially in mountainous countries such as Iran. Some information is currently available about the morphological cause and effects of some apparent cases. However, the destructive effects of this phenomenon on ancient settlements have not adequately been mentioned. This study examines an ancient landslide by combining data from two seasons of archaeological excavations of Tepe Mehr Ali, located in Fars province, and related interdisciplinary studies. The results of the excavations, geological evidence and morphology of the site indicate that the southern slope of the mound (about 35 degrees) to Balangan River, represent a landslide event leading to the abandonment of this site for some time during settlement periods.
