Social trust is a crucial aspect of human relationships, underpinning participation and cooperation among community members. It accelerates involvement in economic, social, political, and cultural fields and enhances interactions across diverse groups within society. In the absence of trust, democratic systems, social stability, balance, and solidarity are unlikely to flourish. Media plays a significant role in developing social trust, either enhancing or eroding it by presenting favorable or unfavorable images. This study compares print and social media and their relationships with social trust levels. The survey, conducted among Tehrani respondents aged 18 to 60, used a sample of 356 based on the Cochran formula. Random sampling was validated by authorities, with reliability estimated at 0.74% using Cronbach’s alpha. Results indicate a direct relationship between social trust levels and print media usage, while social media exhibits an inverse relationship. Trust levels among males using print media are higher than those of females, whereas the opposite is true for social media. To enhance social trust, media should address public interests, needs, and tendencies. Analyzing social media content in relation to governmental approaches to public areas is essential for increasing social trust.

Urban expansion often leads to significant environmental and social challenges, including increased built-up areas, reduced green spaces, and strained public services. This study focuses on the urban expansion of the Beirut Southern Suburb over a period of more than 50 years using Remote Sensing (RS) and Geographic Information Systems (GIS). By analyzing land-use changes and road network expansions from 1963 to 2016, the study highlights the increase in impermeable surfaces and the subsequent rise in flood risks. The research utilizes areal and satellite imagery to compare historical land-use and road network maps. Findings indicate a substantial growth in built areas to accommodate population increases, a decline in green spaces, and a rise in unauthorized constructions and property-related violence. These transformations are largely driven by an influx of residents and inadequate urban planning. The study proposes modifications to building regulations as a strategy to curb unchecked urban sprawl and mitigate its negative effects.

In this paper a case study of a company was studied to improve its production capacity to reach the optimum. Different aspects were investigated, including the speed of the running machines, the number of workers running each machine, the operating shifts, the machines utilization and the working environment. Data were collected for the current situation, then suggested solution were implemented and effect on improving the production capacity was realized. It was found that all these factors have significant effect on improving the production capacity. Machines should be utilized effectively and run at the optimum speed, to improve the production and avoid extra maintenance cost. Moreover, as the working environment is improved as the productivity of workers is getting better, which will be reflected on the company overall production.
