Background and Objective: Today, cyberspace and social networks and satellites, as one of the hallmarks of modern communication technology, have a powerful place in human personal and social life, affecting the personal and social lives of individuals and families. The purpose of this study was to investigate the role of satellite use and social networks in marital satisfaction and intimacy. Methods: The method used in this study is descriptive correlational. The statistical population of the study consisted of all married women in Qom in 2019, out of whom 144 were selected as the statistical sample by available sampling method. Enrich Short Form Marital Satisfaction Questionnaire and Bachelor Marriage Intimacy Questionnaire were used for data collection. The data were analyzed by Pearson correlation coefficient and multivariate regression. In this study, all ethical considerations were observed and no conflict of interest was reported by the authors. Results: The findings showed that the effect of amount of cyberspace use on intimacy variable (P=0.02) and marital satisfaction (P=0.000) was significant, meaning that with a one-unit increase in the amount of space use and satellite, intimacy decreases, and this trend also applies to marital satisfaction, meaning that marital satisfaction is reduced as the result of the use of cyberspace and satellite. Conclusion: Therefore, it can be stated that excessive use of social networks can have a negative impact on the family institution and create an innate conflict for couples.

Leishmaniosis is a common parasitic disease in tropical and subtropical areas of the world caused by protozoan of the genus Leishmania and transmitted to human via the bite of the species of sandflies. This is a zoonotic disease subsumed by the World Health Organization (WHO) in the list of 6 important infectious diseases in the world. The population of the insect vector of this disease is influenced by changes in climate, and has a very strong relationship with climatic factors. The current study aimed at verifying and explaining the feasibility and capability of satellite imagery and data to contribute to identifying, analyzing, and explaining the impacts of climatic factors, and its spatial distribution on the prevalence of leishmaniosis in Ilam province, Iran.
For this purpose, the climatic data including air temperature, soil temperature, relative humidity, precipitation, wind speed, and global solar radiation from 8 meteorological synoptic stations along with the NDVI and LST products of the MODIS sensor for a 3-year period, from 2011 to 2013, were gathered and used. To carry out the current study, at first, raster of all the data were created in Arc GIS 10.2; then, the correlation between the average of raster’s pixels of satellite and stationary data with the raster of leishmaniasis prevalence in a seasonal and temporal scale was verified and analyzed, using the Pearson correlation coefficient. At the end, to identify and model the variables affecting the incidence of leishmaniasis, a multivariate regression model of the prevalence of leishmaniosis was designed for the studied area, based on the correlated variables.
The results for the entire studied area in a seasonal temporal scale showed a negative strong correlation between leishmaniasis prevalence and soil temperature, air temperature, and wind speed (with correlation coefficients of -0.760, -0.756, and -0.691, respectively), and a strong positive correlation with relative humidity and precipitation (with correlation coefficients of 0.660 and 0.662, respectively). Also, wind speed was verified as a limiting factor for leishmaniasis prevalence.
The obtained result showed that the remote sensing data, particularly the LST product from MODIS sensor and rainfall data from TRMM satellite, had acceptable capabilities to be replaced with meteorological stationary data and they also helped to explain and identify factors influencing the prevalence and distribution of spatial patterns of the disease.

According to formation of emerging communication tools and their effects in community, this study aimed to investigate the use of these tools (cell phone, internet and satellite) among young adults in Torbat-e-Heydarieh and its relation with anxiety, depression and stress. In this descriptive-correlative study that conducted in Torbat-e-Heydarieh (summer 2014) numbers of 209 young adults (129 men and 80 women) were selected through randomized sampling method and they fulfilled the questionnaires of Depression, Anxiety, Stress Scale (DASS-21), Yang Internet Addiction, Cell Phone Internet Addiction and demographic form. Data analyzed by descriptive statistics, t-test sample group, one factor variation analysis and Pearson coefficient. The use of cell phone, internet and satellite among young adults in Torbat-e-Heydarieh were higher than mean of our community. Also the use of these tools among men and range of age 20-30 years were higher significantly (P=0.000). In addition, results showed that the anxiety scores were higher in use of cell phone and the anxiety and stress scores were higher in use of internet, and the depression and stress scores were higher in use of satellite significantly (P<0.05). Based on the results the use of emerging communication tools is high and increase of use of them relates to higher scores of stress, depression and anxiety.
