Individual and household coping strategies are essential when dealing with such a crisis. This systematic literature review synthesizes published evidence on coping mechanisms and food security in pandemic situations and looks at future research directions based on the gaps found. The number of publications on coping strategies and food security has increased over time, especially during the Covid 19 pandemic. This topic interestresearcher and academics from various countries and disciplines. Data analysis was carried out using the endnote X9 version following the preferred reporting items for systematic review and meta-analysis (PRISMA). The data was collected from the Proquest, Ebscohost, and Scopus databases. This review’s result is that most publications are in the 2019-2022 timeframe, area of health sciences, quantitative methods, empirical data, and individual case studies. The following review is an analysis based on the research context divided based on sub-criteria: pandemic impact, the main outcome, geographic location, economic development, and basic theory. The findings show that the impact of the pandemic that has been widely studied is about environmental quality and socioeconomic impact; no mention of theory; food security; in Asia; high-income and low-income countries; with the aim of policy development. The next review analyzes the main outcomes of food security and coping strategies. Based on this review, the most studied dimension of food security is accessibility using the HFIAS instrument and cross-sectional survey research design. Furthermore, there are fewpublications on utility and stability dimensions, especially the relationship between the four dimensions of food security, availability, accessibility, utility, and stability, qualitatively and quantitatively. In addition, publications regarding the relationship between food security from its four dimensions and coping strategies both qualitatively and quantitatively are also very limited. These findings create opportunities for future researchers to study them.

“…The productivity of human resources for companies has been investigated with different methods and approaches. Pharmaceutical companies have also been studied and analyzed more in terms of productivity and resources, but less research has been done to compare the indicators and the productivity level of these companies and its relationship with their stocks (Sarfaraz et al, 2022;Mozhdeh et al, 2021). With the complexity of competition in the field of business, especially in pharmaceutical industries and knowledgebased organizations, the role of intangible capital has become stronger than ever before.…”

The methods of library study and review of documents and the content of the materials, as well as the preparation of interviews were used to collect information. By reviewing the subject literature and interviewing managers and experts of some pharmaceutical companies, the components affecting the productivity of human resources have been determined and by brainstorming, the three components of the motivational system, work commitment and job enrichment have been determined in priority. The value level of pharmaceutical company’s stocks, is determined by the ratio of price to profitability, book and accounting value of companies and their market value. With statistical analysis and hypothesis testing, the significant relationship between the productivity components of human resources and the value levels of pharmaceutical companies have been confirmed. The results of the analysis show that unlike other companies accepted in the stock market of Tehran Stock Exchange, where the components of industry, politics and economy are effective in their success and value, for pharmaceutical companies, human resources and especially their level of expertise play a major role in the level of value.
