Introduction:

 Environmental crisis is one of the most important challenges that humanity is facing in this century. The way to face this environmental crisis is definitely decisive in the quality of life of the current and future generations. Many of these environmental problems are rooted in the lack of awareness and cultural weakness in the relationship between humans and nature.

Purpose of the research: 

The goal is to know the causal conditions in order to promote the culture of preserving the environment and natural resources.

Methodology:

 The approach of the current research is qualitative and the data theory method based on the systematic approach of Strauss and Corbin is used as the research method.Geographical area of research The geographical scope of this research is related to the local communities of users all over the country of Iran.

Results and discussion :

Causal conditions in this research, which are the reasons that motivated the researcher to conduct this research and made him seek to provide a model for the central phenomenon of media education. Therefore, the results obtained from among the categories extracted from all the interviews showed that in the media dimension, economic dimension, managerial dimension and social dimension of the main categories, the causal conditions of the media have been obtained and used in order to achieve the goals.

Conclusion:

 Managers' use of media and public relations and media analyzes of the environment play a fundamental role in good environmental governance. Therefore, the most rational thing is to give the highest value to the media as background factors for the maintenance of national resources.

The aim of this study is to analyze media strategies and their effect on promoting environmental culture and natural resources. For this purpose, the data theory method of the systematic approach of Strauss and Corbin (1988) has been used in the interpretive paradigm based on qualitative methodology. 31 in-depth and semi-structured interviews were conducted with media and environmental experts, sociology, culture and media professors, experts from environmental protection organizations, forests, rangelands and watershed management, as well as experts from the General Department of Natural Resources and Watershed Management of Isfahan Province. The interviewees confirmed the interpretation of the interviews to assess the validity, and at the end, a summary of the formulated model was presented to several professors, and their opinions were collected for correction and adjustment. The main topic of the research was "Media and the promotion of environmental culture and natural resources." Research strategies include environmental education from childhood, audience studies, holding art festivals, producing movies and series, creating an environmental group in the media, launching multimedia services, highlighting the halal and haram environment in the Jurisprudence, publishing the effects of environmental and natural resources destruction, creating a campaign, educating journalists, preserving the appearance of environmental factors and natural resources, promoting environmental literacy by analyzing natural resources and environmental issues, reforming the thinking of abundant resources, characterization, production Qualitative content, prioritization of national media, presentation of green life plan, behavioral modeling of employees of responsible organizations, funding and support of media, creation of media communication system and environment and natural resources obtained from coding steps.

Nowadays, pozzolans are used as cement replacement materials. In recent decades, a large number of studies have investigated the effect of nano silica on the properties of cement based materials. In many cases it has been shown that the use of nano silica as a pozzolan could improve the properties such as mechanical properties and durability of concrete and it has caused to increase service life of structures. Due to the large variety of nano-silica, some of them such as nano silica gel have been studied scarcely. Nano silica gel could have widespread applications, especially in dry mortars. The aim of this study is to provide a method for the production of nano-silica gels and their effects on the properties of cement mortars. The results indicate the good performance of nano silica gel in the process of compressive strength development at early ages. Furthermore, the microstructure was improved considering the results of water permeability and Rapid chloride Migration Test (RCMT) at 28days. By increasing the percent of substitution, strength properties and microstructure were improved.
