The purpose of this study is to analyze the challenges of political marketing with the approach of using the soft power of the Islamic Republic of Iran. Categories related to each of them were extracted using content analysis method and these 6 groups were ranked using Friedman test by SPSS26 software. According to the results, the highest ranking was given to the techniques used in international political marketing with the approach of diplomacy, media power, ideological power, cultural power, economic power and management system power. Persuasion and third place became the most prominent dimension of international political marketing, namely national identity. Iran's current position in terms of identity, international prestige and economic identity ranks fourth, restrictions on the use of political marketing ranks fifth with unique ideological approach, financial challenges and theoretical poverty and the most effective Iranian foreign policy discourse ranks sixth with de-escalation and balance discourse approach. Finally, the analytical model of political marketing affected by limitations, necessities and the most significant dimension using effective techniques and the best discourse in promoting Iran's current position in the economic field and strengthening the international image are presented. Practical suggestions are also provided based on research questions for the Ministry of Foreign Affairs, the Economic Deputy of this agency and non-governmental organizations including the Red Crescent and other responsible agencies and organizations.

The measurement of multidimensional poverty in 22 districts of Tehran is the main goal of this research. Studying human deprivation regarding basic needs i.e. health, nutrition, education and political freedom seems essential due to existing shortcomings of income-based poverty measurement approach. Here, we measure multidimensional poverty in terms of four attributes (income, housing, education and public health) using information theory approach developed by Maasoumi and Logo(2006) model. First, we calculate single-dimensional poverty based on each attribute. Then, according to difference in levels of substitutability among attributes we measure the absolute poverty using aggregate poverty line approach. The results show that the poorest districts of Tehran are district 19 in terms of income approach and districts 19 and 17 in terms of education and housing, respectively. The worst situation regarding public health belongs to district 16. The highest and the lowest multidimensional poverty rate were observed in districts 4 and 1 respectively. Furthermore, if substitution coefficient among attributes increases, then the multidimensional poverty rate will decrease. About 63 percent of Tehran population is of relative deprivation.

The aim of the present study was to investigate the physicochemical and sensory properties of yogurt fortified with chia seed mucilage and oil, as a rich source of omega-3 fatty acids. For this purpose, mucilage (0.213%), free and encapsulated oil (3.41%) were added to the yogurt formulation. The prepared sampleswere compared in terms of some physicochemical (pH, titratable acidity, syneresis, dry matter, peroxide values and color attributes) and sensory properties with control (without oil and mucilage) during storage for 30 days at refrigerator temperature (4 °C).The results showed that the addition of mucilage and chia seed oil in a free and encapsulated forms caused a significant increase in water holding capacity (decrease in syneresis), acidity (decrease in pH) and dry matter during storage (p <0.05). In addition, the sample containing mucilage and encapsulated oil showed the lowest color difference (∆E) with the control. Furthermore, this sample showed an increase in whiteness index (WI) and a decrease in yellowness index (YI) compared to the sample containing free oil. The amount of peroxide value in the samples containing free and encapsulated oil after 30 days of storage was 3.19 and 1.16 meq / kg of oil, respectively, which indicates the protective effect of encapsulation process against oxidation of samples. Evaluation of sensory attributes showed that the addition of mucilage and encapsulated chia seed oil did not have significantly effects on the sensory properties of fortified yogurt samples (p˃0.05).
