Nanotechnology in the food industry provides a logical framework for developing an understanding of the reactions and self-arrangement behavior of small-scale food components. The purpose of this study is to identify and rank the factors affecting the improvement of food security based on the role of nanotechnology. The statistical population of the study was all the specialists of the Special Staff for Nanotechnology Development, whose number was 90 and due to the limited community of specialists of the Special Staff for Nanotechnology Development, they were selected through census. The present study is a descriptive correlation that a researcher-made questionnaire based on the theoretical framework of the research was used to collect data. Validity and reliability of the questionnaire indicated that the measuring instruments had good validity and reliability. The results of the research using SPSS software and prioritization of items based on coefficient of variation (CV) showed that in food storage, covering fruits and vegetables with nanocytosan containing copper was more important, also in Food processing, protection of nutrients against oxidation, in food production, production of biocompatible pesticide formulations, in food flavor and color improvement, nano-encapsulation of various fragrances and flavors in food to control the release of fragrances Flavors were more important in food health, the use of nanosensors to detect pathogens in food and in food packaging, the use of nanoparticles with antimicrobial properties of packaging.

Although there is general agreement on the importance of the strategic management system in organizations, but still there is a gap in the role of strategic management in the education system. This research tries to identify, categories and modelling the functional approach and factors affecting on implementing strategic management in educational system using grounded theory qualitative method. MAXQDA 10 was used to analyses data. based on 12 interviews with some faculty members in Ferdosi university168 concepts among 15 main categorize were identified. Also these concepts are structured according to the paradigm model grounded theory in six dimensions including "casual conditions", "phenomenon", "Strategies", "context", "intervening factors" and "consequences".In the form of strategic management paradigm model including intra-university and extra-university factors as causal conditions, process and structural strategies, management and human resource development, leadership and management style, control systems, as implementation strategies and organizational culture, management system Knowledge and information, innovation-oriented approach as an intervening condition, environmental factor as contextual and economic consequences, socio-cultural consequence, structural structural consequence and achievement of goals and promotion of the university as the consequences of strategic management system through Foundation data theory have been identified.

Pomegranate is one of the most important strategic agricultural products of Tarom Township. Despite the important place of this product in the livelihood of rural households, the marketing of this product, like other agricultural products in Iran, has many problems. Any planning in the field of improving the pomegranate market requires understanding the marketing behaviors of pomegranates. Therefore, this descriptive-correlational study was conducted to investigate the factors affecting the marketing behavior of pomegranates in Tarom Township. multi-stage random cluster method was done in sampling stage and the number of samples was selected and studied using Cochran's formula of 160 people out of 5207 people whit step by step and according to the number of farmers in rural areas and villages. Data were analyzed by survey using a structured questionnaire whose validity and reliability were confirmed and using SPSSWin22 software. The results showed that the variables of pomegranate sales point, financing sources, water supply source, access to credit and financial services, receiving loans from banks and financial institutions, pomegranate history, annual agricultural income, approximate distance from garden to sales center, total garden performance The rate of self-consumption of pomegranate, the cost of transporting pomegranate to the market for sale and the use of local intermediaries in the village to obtain information have a positive and significant relationship with the marketing behavior of pomegranates.

The purpose of this study was to analyze the content of the TV-agricultural program Talash-e-Sabz, which produces in the Jihad Group of Khorasan Razavi TV. The statistical population of the study included Talash-e-Sabz programs broadcast from September 2017 to September 2016. Sampling was random and included selecting one part of the program per month. Finally, 12 parts of this program were reviewed and content analysis. Results indicated that among the various items of the program, the presenter's speech occupies the largest percentage of the program time, and the interview with experts, show section and the speaker's speech are in the next categories. Among the axes in question, the axis of horticulture has been in the highest priority, while the axis of food and conversion industries has been the lowest priority. The results of the content separation of the studied programs in terms of topics showed that the usual thanksgiving and socializing with viewers and farmers had the highest frequency during the program and then, issues related to planting, holding and harvesting horticultural and agricultural products, the economic importance of agriculture, livestock and the environment and its place in the exchange rate and turnover and production goals of agricultural and livestock products have had the most repetition in the program, respectively

The purpose of this study was to design an adaptive capacity model of wheat farmers in Mehran city in confronting with particulate matter and its effective factors. The statistical population included wheat farmers in Mehran city including 315 people for 14,500 hectares of wheat lands. The sample size was estimated 173 of wheat farmers using the Cochran formula which increased to 180 to enhance the accuracy of the calculation. The random sampling method was used. The collected data were analyzed using SPSS and AMOS software. Bootstraping technique was used to evaluate the significance of path coefficients. Educational-extension mechanism (path coefficient = 0.446 and t-value = 3.409) and agronomic mechanism (path coefficient = 0.428 and t-value = 2.470) show a significant effect on adaptation to fine dust phenomenon have given. While the effect of managerial mechanism (path coefficient = 0.153 and t-value = 1.391), technical mechanism (path coefficient = 0.118 and t-value = 0.637) in this regard was not significant. Factors such as lack or lack of awareness, education and communication and extension weakness, conducting research without considering the adaptation and needs assessment and not simplifying their results for farmers, not considering the required credit and capital, not paying attention to adaptation to the phenomenon of fine dust. As a necessity, the lack of infrastructure to pave the way for implementation of activities compatible with the phenomenon of fine dust and the disproportionate tariffs for agricultural insurance can play a significant role in the non-significance of these mechanisms. However, the structure of adaptation to the fine dust phenomenon directly and the mechanisms related to it indirectly had very significant and significant effects on the adaptability.
