The evolution of food security: where are we now, where should we go next?

Food security is one of the most challenging topics globally; however, the concept of food security has taken on additional dimensions that are general and are less detailed. This study aims to identify the intellectual structure of food security research and the changes in this structure. This paper analyzed 3169 documents from the Web of Science database through a bibliometric review. A review of the published documents shows an increasing trend over the past 46 years. In accordance with co-occurrence analysis, 125 keywords were grouped into five clusters: food security and sustainable development; food security and socioeconomic factors; food security policy and governance; coping strategies for poverty, inequality, and hunger; and modern food security management. This study identifies four streams within food security research: sustainability and environmental, socioeconomic, cultural, and political factors. The paper concludes that even though food security might investigate many significant areas, other new dimensions should still be considered. Further gaps in the literature emerge that present avenues for future research directions. Reviewing indicators and techniques of food security assessment and identifying high-risk groups should be a priority

The study of comparison between the dimensions of life satisfaction in coronary artery patients and healthy people

The purpose of this research was to compare Life Satisfaction in coronary artery patients and healthy individuals. It is an experimental control study. The experimental group was 50 men and women having coronary artery disease, referring to heart clinic in Motahari Hospital located in Fooladshahr. The control group was healthy men and women living in three sites of Fooladshahr. Experimental and control group were similar regarding gender and they were all married. They were all selected by available sampling. The data was gathered using Feriseh’s Life Satisfaction Questionnaire. The evidence related to its validity was studied by using simultaneous validity and to its reliability by cronbach’s alpha which were both accepted. Multi variable variance analysis, controlling age and education, showed that Life Satisfaction in experimental group was significantly lower than control group. Since, the results showed that Life Satisfaction was significantly lower in coronary artery patients in terms of factors like physical health, self- esteem, work, play, money, love, spouse are lower in heart chronic patients, it is understood that Life Satisfaction is a related factor to this disease. Also, the result clarified there were not significant differences in factors such as goals and values, learning, creativity, helping, children, relatives, home, neighborhood and communit
